[Bug 28493] Freeze when adding menu to panel from Ubuntu main menu icon
Public bug report changed: https://launchpad.net/malone/bugs/28493 Comment: Those packages did help me get better backtraces. Here are a few, they do look very similar to each other. These were taken at the point of failure, whilst the process was spinning (i.e. I attached 'gdb' to the running process, then triggered the bug). Hope this helps, Lambros Program received signal SIGINT, Interrupt.

Public bug report changed: https://launchpad.net/malone/bugs/28493 Comment: Oops, sorry, that might have been a red herring. That third assertion is printed as soon as I click on the Ubuntu logo to drop down the main menu, not at the time of triggering the lockup which occurs later after clicking through the sub-menus. I can get a stack-trace from the Ctrl-Alt-F1 console running gdb, and doing Ctrl-C while gnome-panel is spinning. But I don't know how to capture it to be able to send it to you. But it's very similar to the one I already sent. And still not many source files and line numbers. I'm working on this...

[Bug 28493] Freeze when adding menu to panel from Ubuntu main menu icon
Public bug reported: https://launchpad.net/malone/bugs/28493 Affects: gnome-panel (Ubuntu) Severity: Normal Priority: (none set) Status: Unconfirmed Description: I'm using Ubuntu Breezy 64-bit, with backports enabled. If you are just browsing these bug reports and are new to Linux, please DO NOT follow these directions! They cause a complete desktop freeze, and a machine reboot will not recover your desktop! To reproduce: (the problem happens every time for me) Create a new user account, log out then log in as the new user (this is simply to recreate the default Ubuntu settings). Right-click near the middle of the top panel and choose Add to panel Choose Main Menu with the Ubuntu logo (NOT the Menu Bar next to it) and add it. Click on the newly-added icon on your panel, go to System - Administration and right-click on Add Applications. Go to Entire menu and choose Add this as menu to panel. My desktop immediately freezes at this point. Symptoms: Desktop becomes unresponsive to any mouse-clicks (although the mouse-cursor still moves about). After rebooting the system and logging in, the desktop shows blank grey bars at top and bottom, where the panels would have been drawn, and an endless series of error dialogs is shown. The top command shows that gnome-panel is consuming 99% CPU, so it is evidently stuck in an infinite loop. The only way that I know how to recover the desktop is to go to init 1. Then cd to /home/user/.gconf/apps/panel/objects In that directory, there are lots of object_NN directories. Find the one that was most recently created (e.g. with ls -lt) and then delete it. That procedure cures the problem for me. gnome-panel --version gives Gnome gnome-panel 2.12.1. The version according to Synaptic is 2.12.1-0ubuntu7 (breezy) I can figure out how to get a stack-trace using ddd and attaching to the spinning gnome-panel process. Please let me know if you want this info, but I'd prefer to know if there's a more convenient way to get this (I'm not very familiar with Linux command-line debugging tools, sorry :-). This problem appears to be specific to the Main Menu panel item, and doesn't seem to happen with the Menu Bar item which is used by default and looks the same but with the Applications Places System text showing.

Public bug report changed: https://launchpad.net/malone/bugs/28493 Comment: Here's the backtrace. I installed gnome-panel-dbg but wasn't exactly sure what to do with it. I've also attached my most-recently-created object_xx folder. Looking at the xml file, there is an entry with name=position and value=-1. I wonder if gnome-panel got stuck trying to work out where to place the new menu item?
