Hello,
I tested the newest revision and the bug was NOT fixed.
I than changed the time delay in line 691 of explorer.py from 50ms to 200ms.
No the bug seams to be fixed.
Thank's for the good work!
Best regards:

Hello,
this could also be a bug in Spyder. Citation:
"
The passive nature of models provides new challenges for programmers.
Inconsistencies in the model can cause the application to crash.
Since the model is hit by numerous calls from the view, it is
hard to find out which call has crashed the application and which
operation has introduced the problem.
"
I think it could be worth to run the model that is implemented
for the treeview of the project explorer with ModelTest for
Python, see:
http://code.google.com/p/modeltest-pyside/
But I am happy with the workaround (close all open projects
before closing spyder) for now.
Some more details:
3.5 Debugging with ModelTest
The passive nature of models provides new challenges for programmers.
Inconsistencies in the model can cause the application to crash.
Since the model is hit by numerous calls from the view, it is
hard to find out which call has crashed the application and which
operation has introduced the problem.
Qt Labs provides software called ModelTest, which checks models
while your programming is running. Every time the model is changed,
ModelTest scans the model and reports errors with an assert.
This is especially important for tree models, since their hierarchical
nature leaves many possibilities for subtle inconsistencies.

Thanks Uwe for finding the real source of the problem. It's really helpful
for us.
Unfortunately I couldn't reproduce the problem following the instructions
you gave to us, although I'm using Kubuntu and you are in Ubuntu, which
could be an important difference. I have a virtual machine with Ubuntu 12.04
so I'll try to check it out later there.
In any case, I agree with Tim that this seems more of a Qt problem than a
problem with our code, so we probably can't fix it.
Cheers,
Carlos

when starting with the debug option I get one error shown (sometimes, when

the program) which might be related or not:
I do not see this nor do I personally understand the messages.
So the others may need to help.
But I would still suspect that things are with the QT libs.
Sorry.
Hello,
I did some more testing.
The bug appears only under the following conditions:
1. The window "Project explorer" is shown when closing Spyder.
2. There are at least two projects shown in the "Project explorer".
3. At least one of the projects must be open and must contain at
least one file when closing Spyder.
Exactly under these conditions the bug appears.
If I close the projects (the tree view) so that none of the containing
files is shown in the "Project explorer" when closing Spyder than
no crash occurs. Otherwise it crashes on every second launch.
It doesn't matter how many files are open in the editor.

Uwe Fechner
