[Bug 990960] Re: openBVE crashes, another dependency issue?
I think there a t least 3 problems reported here
Concerning the following problem
>System.NullReferenceException: Object reference not set to an instance of an
>object
> at System.Windows.Forms.ListView+ItemControl.ItemsMouseDown (System.Object
> sender, >System.Windows.Forms.MouseEventArgs me) [0x0] in unknown>:0
Other mentionned bugs should have been reported elsewhere for other bugs
(duplicates ?)
Ubuntu 15.04
+ OpenBVE 1.4.0.9-1 as installed
I reproduce this bug each time i try to select a route with the mouse (not with
the keyboard)
After having tried to localize the problem with monoDevelop, i think
i've found something that could cause the problem
When i read the source code, i see
OpenBve/OldCode/formMain.Start.cs,
private void ShowRoute(bool UserSelectedEncoding) {
if (Result.RouteFile != null) {
this.Cursor = Cursors.WaitCursor;
Application.DoEvents();
]...[
C# Microsoft documentation suggests this code (Application.DoEvent call ) could
cause problems
https://msdn.microsoft.com/en-US/library/system.windows.forms.application.doevents%28v=vs.110%29.aspx
You will find many posts on many forums about this topic
>Calling this method causes the current thread to be suspended while all
waiting window messages are processed. If a message >causes an event to
be triggered, then other areas of your application code may execute.
This can cause your application to >exhibit unexpected behaviors that
are difficult to debug.
What i see is that removing this instruction (Application.DoEvent call) seems
to remove the problem and allowing to show the route.
As i'm not a premium developper i'm not directly going to change the code for
OpenBve.
If anyone could validate or not the code ??
-- Code suggested
private void ShowRoute(bool UserSelectedEncoding) {
if (Result.RouteFile != null) {
this.Cursor = Cursors.WaitCursor;
if (!Program.CurrentlyRunningOnMono) { //
disabled code on Mono because it makes crash
Application.DoEvents();
}

[Bug 990960] Re: openBVE crashes, another dependency issue?
Hello, Instead of creating another thread I decided to join this one.

Paul, I have not been able to reproduce the bug yet (I followed your exact same procedure, starting from a fresh Ubuntu 12.04 VM with all updates, with these differences: -I let OpenBVE select the train automatically instead of choosing it manually, but checking that LT1995 got selected; -I tried loading all three routes of the Northern Line in the 1995TS routes folder, restarting OpenBVE after each try). I have looked more carefully at the Northern Line package and noticed that there are other three routes in the 1995TS routes visible prior train folder (I'll try to repeat the test with them later). Jamie: 1) Are you perhaps trying to load one of the routes in the 1995TS routes visible prior train folder? 2) Which specific route is causing the crash? 3) Could you please check that the Northern Line package has been downloaded correctly?

[Bug 990960] Re: openBVE crashes, another dependency issue?
I've tried loading the three Northern Line routes downloaded from http://www.trainsimstuff.org/lu-northern-line/northern-line-downloads; no errors occurred. However, I noticed a strange behaviour: when running low on memory, OpenBVE tends to crash with Divide by zero exceptions (I actually experienced it once, when I set the VM to have only 512 MiB of RAM); maybe that's the cause. I also checked the OpenBVE forums and found that some users, in the past, reported crashes on the Northern Line when using brakes: http://openbve.freeforums.org/problem-using-northen-line- lt1995-t1291.html (the forums are temporarily down, don't worry if you can't reach the thread just now). I actually tried to apply brakes to check the program's behaviour and experienced no crashes. Could you please check: 1) whether you're working with the latest version of the Northern Line package, and 2) whether you've placed all the package files in the right place? If yes, could you please attach a Mono backtrace? It would be helpful - open a Terminal and launch OpenBVE like this: mono --debug /usr/lib/openbve/OpenBve.exe /filesystem=/etc/openbve/filesystem.cfg Then try to reproduce the crash, the backtrace should be generated as soon as OpenBVE raises an exception; it should be displayed in the terminal or saved in a file into the directory OpenBVE was launched from (I could not find additional information about that). After that, please attach the backtrace here. Also, 3) were you trying to applying brakes when OpenBVE crashed, and 4) how much memory have you got, and how much of it is free at the time you run OpenBVE (check it with the top -n 1 command)?

[Bug 990960] Re: openBVE crashes, another dependency issue?
Jamie: we really need to be able to reproduce this under a debugger. Would you be able to describe (for an idiot like me) the exact sequence of steps necessary. Preferably in command-line form so that they can be more easily replicated; eg. something like: 1. sudo apt-get install openbve 2. cd ~/somewhere 3. wget somewhere/something.zip 4. unzip asdf 5. openbve 6. click once on X, Y, Z 7. crash occurs At this stage we don't know (I think) if it's in Openbve itself, or in one of the general Mono libraries. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/990960 Title: openBVE crashes, another dependency issue?

Alessandro: No, it crashes when loading the route (I have the latest version) and the train (both also crash when used separately). Also, I get no backtrace when loading OpenBVE up like that, just the crash. I'll grab the memory amount and post it here in a minute (I won't tell you much with multiple processes running). Paul: 1) Make sure you have the latest Northern Line package. 2) Launch OpenBVE. 3) Click on of the northern line routes. 4) Launch it. 5) It will probably crash. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/990960 Title: openBVE crashes, another dependency issue?

Not sure as the crash occurs in the Timetable management class, where no references to external libraries should be present. I'll test this as soon as I can have access to a high bandwidth connection and upgrade my workstation to Precise (should be between the 2n and 3rd of May). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/990960 Title: openBVE crashes, another dependency issue?
