Application: gwenview (2.9.0)
KDE Platform Version: 4.9.00
Qt Version: 4.8.1
Operating System: Linux 3.2.0-27-generic x86_64
Distribution: Ubuntu 12.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
I was trying to upload pictures to my PicasaWeb albums. First, I selected all the photographs I want to upload then from the Export menu I chose the PicasaWeb option. After I login, choose the folder and click the Upload button, Gwenview crashes. Every single time. 
- Unusual behavior I noticed:

The crash can be reproduced every time.

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