KDE Platform Version: 4.4.2 (KDE 4.4.2)

-- Information about the crash:
If I have two instances of Parley running and then I close one of them, Parley crashes. I do not open Parley twice myself, but when I restart my computer with Parley running, this happens.

The crash can be reproduced every time.

 -- Backtrace:
