--- Comment #9 from Christian Reiner <reiner imageware de>  2009-06-16 10:43:04 ---
Some additional information: 
1.) The crash is 100% reproduceable for me under conditions of 2.) It happens
exactly every second (!) time kontact is started. That means: after closing
kontact the first attempt to start crashes, the second one succeeds. 
2.) The crash seems to occur only, if akregator has been started inside
kontact. 
3.) It appears to me that starting something like "kmail --composer" directly
instead of kontact is not possible, only starting the kontact shell seems to
fix the problem to allow success with the second try.
