Bug 316203

Application: kphotoalbum (4.2)
KDE Platform Version: 4.10.00
Qt Version: 4.8.3
Operating System: Linux 3.5.0-25-generic x86_64
Distribution: Ubuntu 12.10

-- Information about the crash:
Running on Kubuntu 12.10.

- What I was doing when the application crashed:

When kipi-plugins is installed, KPhotoAlbum will crash when the plugins menu is selected.

If I open KPhotoAlbum's plugin configuration and disselect all the plugins, KPhotoAlbum will not crash.  However, if I activate just one plugin from the list (any one, it's not tied to any specific plugin), and "apply" or hit "OK", the progam crashes.

Kubuntu doesn't seem to have KPhotoAlbum debug symbols, so I hope the traceback is helpful.

The crash can be reproduced every time.

-- Backtrace:
Application: KPhotoAlbum (kphotoalbum), signal: Segmentation fault
