Bug 218860

Application: digikam (1.0.0-beta5)
KDE Platform Version: 4.3.80 (KDE 4.3.80 (KDE 4.4 Beta1))
Qt Version: 4.6.0
Operating System: Linux 2.6.31-16-generic i686
Distribution: Ubuntu 9.10

-- Information about the crash:
I'm tring to run digikam from krunner. Before if crashes, a message on the system tray is displayed saying:
Nepomuk Semantic Desktop needs the Virtuoso RDF server to store its data.....

Right after that, the crash report shows up. I can start it from the command line and it doesn't crash.

The crash can be reproduced everytime.

 -- Backtrace:
Application: digiKam (digikam), signal: Aborted
