-- Information about the crash:
Launcher often slows down and does not respond to typed input.  Sometimes it unfreezes after some time (say 30 sec). In this case I typed 'konq' and it crashed before I completed the command. This is a much more straightforward usage than described in other reports.

The crash can be reproduced some of the time.
