--- Comment #25 from Dan Kegel dank@kegel.com 2008-07-29 10:20:49 --- That X crash could be caused by a system problem. What version of Linux and X are you using?
If it's a Wine bug, a log like WINEDEBUG=+sync,+x11drv,+relay wine ~/C/Programme/jana2006/jana2006.exe might help pinpoint the offending call.
