Comment 1 Dario Andres 2009-12-24 20:22:52 UTC

This is a weird one. Probably a bug in the Qt library..
- Have you tried to repeat the situation and check if it crashes again ?
Thanks

Comment 2 Roman K. 2009-12-24 23:11:32 UTC

yes I tried it a few times again, but it didn't crash anymore

Comment 3 Dario Andres 2009-12-24 23:12:38 UTC

Ok. Reopen this report if you can reproduce this crash again. Thanks
