Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic i686
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Kontact crashed during launching the program.  This seems to have happened a few times in the past.  I just clicked the program to start and it crashed after a few moments during its launching.

The crash can be reproduced some of the time.
