Application that crashed: digikam
Version of the application: 1.0.0-beta4 (rev.: 1009242)
KDE Version: 4.3.00 (KDE 4.3.0)
Qt Version: 4.5.2
Operating System: Linux 2.6.30-1-amd64 x86_64
Distribution: Debian GNU/Linux unstable (sid)

What I was doing when the application crashed:
i added the theme icon to the toolbar.
i changed ALL the theme (twice) i ran up and down the themes listbox with the keyboard's up and down arrows. (worked quickly and without any problems)
when i was happy with the Blue theme. i removed the THEME icon from the toolbar...
the screen flickered (as it always do when i press apply or ok in the toolbar configuration dialog) and then... crash.

 -- Backtrace:
