Bug 305811

Application: gwenview (2.9.0)
KDE Platform Version: 4.9.00
Qt Version: 4.8.2
Operating System: Linux 3.5.0-10-generic x86_64
Distribution: Ubuntu 12.04.1 LTS

-- Information about the crash:
- What I was doing when the application crashed: the application crashed when I was trying to upload photos to fecebook via app's plugin. It is the second time it happens in 2 attempts to use the plugin. Strange is that the export tab in plugins shows in batch processing

The crash can be reproduced some of the time.

-- Backtrace:
Application: Gwenview (gwenview), signal: Segmentation fault
