Bug 280934

Application: digikam (2.1.0)
KDE Platform Version: 4.6.5 (4.6.5)
Qt Version: 4.7.3
Operating System: Linux 3.0.1-3.fc16.x86_64 x86_64
Distribution: "Fedora release 15 (Lovelock)"

-- Information about the crash:
- What I was doing when the application crashed:
Digikam was opened on an album, and I wanted to rename all extension to lowercase
I used the following bash lines (It's ugly, I know, I should have closed digikam...) :
for i in *.JPG; do mv $i ${i%%.JPG}.jpg; done
for i in *.JPG.xmp; do mv $i ${i%%.JPG.xmp}.jpg.xmp; done

After the first one was issued, digikam crashed

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
