Bug 328827

Application: digikam (3.4.0)
KDE Platform Version: 4.11.2
Qt Version: 4.8.4
Operating System: Linux 3.11.0-14-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:

According to mail from Christoph Feck, 14.12.13 22:19, stating that "Crash when loading BMP file with alpha channel fixed in QT 4.8.5", I subsequently went through all pathes containing BMP pics, converting these into PNG and/or JPG (all: about 110 pics).

After doing so, digiKam keeps on crashing at start up as described several times before ( .. ).

1.) Does this issue affect other file formats, too?
2.) How to search specificaklly for pics affeteted?
3.) Do you plan to program such an automated pre-check _before_ taking up such files harming integrity of digiKam's database?

The crash can be reproduced every time.
