Bug 338482

Application: digikam (4.0.0)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.15.8-200.fc20.x86_64 x86_64
Distribution: "Fedora release 20 (Heisenbug)"

-- Information about the crash:
- What I was doing when the application crashed:
A camera SD card was inserted in the computer slot.
I started DK (at this point, no album is selected, and the main windows shows no picture), clicked on "import", selected pictures and clicked on "Download and delete selected". DK crashed immediately.
The crash is reproducible everytime.
Workaround : after launching DK, select an album (by default, no album is selected), then import the pictures.
I didn't try to delete digikamrc, since I don't want to :-)

The crash can be reproduced everytime.

-- Backtrace:
Application: digiKam (digikam), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".
