Version:           0.8.1 (using KDE 3.5.1, Gentoo)
Compiler:          gcc version 3.4.5 (Gentoo 3.4.5, ssp-3.4.5-1.0, pie-8.7.9)
OS:                Linux (x86_64) release 2.6.15-gentoo-r5

I installed digikam today. Then I connected and mounted my camera and downloaded the photos to a temprorary album using digikam's Browse dialog. After that digikam crashed with signal 11. I restarted it, but it crashed upon startup. I moved the images from the album to another dir and launched digikam again. It launched fine. I imported the images from where I put them, and digikam didn't crash. I closed and relaunched it several times (just to test), and no crashes occured. As I have -fomit-frame-pointer in my CXXFLAGS, the output of KDE chrash handler won't be very useful, but here it is:
System configuration startup check disabled.

Just tried to reproduce and noticed that it only occures if I select multiple files. Single-file downloads work fine.
