Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Linux Mint 12 KDE

-- Information about the crash:
- What I was doing when the application crashed:
I inserted MicroSD card in reader and connected reader to PC
Device Notifier offered 3 options for opening the microSD
I selected Digikam
System immediately reported Digikam crashed.
I repeated the above steps and received the same result.

The crash can be reproduced every time.

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