Description Matthew Woehlke 2008-09-09 22:18:03 UTC 
Version:            (using Devel)
Compiler:          gcc (GCC) 4.3.0 20080428 (Red Hat 4.3.0-8) 
OS:                Linux
Installed from:    Compiled sources

I'm seeing the assert in DealerScene::setWaiting(bool) (dealer.cpp circa 1118) trip occasionally. It happens sometimes in freecell, but *every* time in simple simon, exactly when a run is completed. This is with r859205.

Here's the last snippet of output plus backtrace (from a gdb run):

savegame for lazy people :-)

This will happen with ANY game of simple simon (it's impossible to complete a game without hitting the bug), but for people who are lazy, here's a game that is 1 move away from completing a run. Moving the Qs-As onto the Ks starts the 'run complete' animation, which trips the assert about halfway through.

Note that I haven't noticed any ill effects from simply removing the assert...
Comment 2 Stephan Kulow 2008-09-10 11:50:45 UTC 
thanks for the savegame, can confirm :)
Comment 3 Stephan Kulow 2008-09-10 12:02:25 UTC 
fixed in SVN: 859425
Comment 4 Matthew Woehlke 2008-09-10 23:54:42 UTC 
Confirmed, thanks!
