Description Tim Ruppel 2004-12-09 00:35:59 UTC 
Version:           1.5.1 (using KDE KDE 3.3.1)
Installed from:    RedHat RPMs
OS:                Linux

Occasionally, after running kshisen for a few minutes, and then quitting, the KDE crash reporter pops up claiming the program segfaulted.

Here is the backtrace:

Comment 1 Tommi Rantala 2005-06-04 16:58:30 UTC 
I always get segfault when pressing Ctrl-Q. Selecting Game->Quit works OK.

Same backtrace, Shisen-Sho 1.5.1 / KDE 3.4.1.
Comment 2 Tommi Rantala 2005-06-04 17:13:43 UTC 
This fixes the crash for me:
