New crash information added by DrKonqi

digikam (2.0.0-beta4) on KDE Platform 4.6.1 (4.6.1) using Qt 4.7.0

- What I was doing when the application crashed:

I was trying ou the new face recognition, and when I confirmed a face for one image, digikam crashed.

Comment 2 Marcel Wiesweg 2011-03-13 16:05:26 UTC 
les: Looks like a valid crash. Could not reproduce so far, but that means nothing in this case. I'm not quite clear if you could reproduce only once, or each time?

Karl: There is an exception thrown and rethrown, rendering the backtrace useless. You need to run digikam under gdb, type "catch throw", then "run", provoke the crash, get a backtrace with "bt".
Comment 3 les 2011-03-13 22:34:29 UTC 
Yes I seem to be able to reproduce this each time. I have just tried 5 one after another - but I cancelled the crash reports.

Comment 4 Marcel Wiesweg 2011-03-13 22:47:57 UTC 
Yes I got it now as well. Too late tonight for thinking, will get back to it tomorrow.
Comment 5 Marcel Wiesweg 2011-03-14 22:37:43 UTC 
Git commit 398f2d97d7f6ebed1057a98a00eecdbb1640280c by Marcel Wiesweg.
Committed on 14/03/2011 at 22:04.
Pushed by mwiesweg into branch 'master'.

Disconnect the animation before deleting it.
Otherwise, the animation may emit the aninmationFinished signal which triggers
object deletion just from within a scope where the same objects are deleted.
This crashes.
