Bug 264656

Application: gwenview (2.6.0)
KDE Platform Version: 4.6.00 (4.6.0)
Qt Version: 4.7.0
Operating System: Linux 2.6.35-25-generic x86_64
Distribution: Ubuntu 10.10

-- Information about the crash:
- What I was doing when the application crashed:
i looked at some pictures using gwenview and tried to publish one using the new kipi plugin
integrated into gwenview.
When i was clicking on "Senden an..." ("send to...") gwenview crashed

This seems to be related, maybe even a duplicate of #264655

The crash can be reproduced every time.

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