Application: gwenview (2.6.0)
KDE Platform Version: 4.6.3 (4.6.3)
Qt Version: 4.7.3
Operating System: Linux 3.0-1-generic x86_64
Distribution: Ubuntu oneiric (development branch)

-- Information about the crash:
- What I was doing when the application crashed:
Going through ~50 photos, and having rotated ~20, I received a drop-down memory warning suggesting that I Save to avoid  losing changes. I clicked "Save All", and briefly saw a progress bar. At some point into the operation (not immediately), Gwenview crashed. On re-opening Gwenview, 18 photos remained in a rotated-but-unsaved state. I am not sure if some were rotated and then saved by the set of operations which failed. 

I am running Gwenview Version 2.6.0
Using KDE Development Platform 4.6.3 (4.6.3)
on Ubuntu 11.10 (development) 
on a machine with 768MB RAM, 2GB swap
