Description Umidjon Almasov 2011-11-17 13:39:22 UTC 
Application: digikam (2.1.1)
KDE Platform Version: 4.7.2 (4.7.2)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-13-generic i686

-- Information about the crash:
- What I was doing when the application crashed: Run digiKam > select photo from My Albums > menu Export > Export to VKontakte... > click Close button (without uploading) - digiKam crashes. Click Export to VKontakte if not connected to internet, "Network Error" dialog appears ("There was a network error when trying to authenticate with VKontakte web service."), when click OK button in "Network Error" dialog digiKam crashes too.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault

I cannot see any code from this plugin in your trace.

Can you try to run digiKam through GDB and get a better backtrace ? Look here for details :
