question-avatar-chooser-hang

[Raluca-Elena Podiuc <ralucaelena1985 gmail com>]

Hi,

For some time now I am trying to understand why the patch I made for
Empathy using cheese-avatar-chooser works only with a virtual camera.
If I try it with a real camera the interface hangs.
I have no idea were the problem is.
I have to test cases: one that works and one that doesn't.
The working test case creates a cheese-avatar-chooser in the callback
of a button.
The one that almost always hangs creates a file chooser, displays it
and then creates the cheese-avatar-chooser.
I attach the code.
When you have time please run it and maybe tell me why one works and
why the other doesn't.
If you have any idea were should I file a bug please let me know.
