Description Julien Bigot 2008-02-20 18:39:15 UTC

Version:            (using KDE 4.0.1)
Installed from:    Gentoo Packages
OS:                Linux

Quite easy to reproduce, so I don't think it's useful to give a lot on informations about my system.
If you can't reproduce, I would be pleased to give more informations.

To reproduce :
 - run bovo (4.0.1 in a KDE 3.5.8 desktop here)
 - press new to start a game
 - ask for a hint with the dedicated toolbar button
 - ask for a new game again
 - look at the beautiful backtrace (compiled without debugging informations here, so it's not as beautiful as it could be)

keep on the good work, and thank you for providing such a great desktop with such great apps !
