Comment 1 oldmanbim 2011-01-23 17:34:53 UTC 
I pushed the "pause" button before the game was started.  Won't do it again, promise!
Comment 2 Frederik Schwarzer 2011-06-29 15:55:55 UTC 
It should not be possible to pause a game before it was started. If it is, it is a bug.

So, can you reproduce the problem without KVM?
Comment 3 oldmanbim 2011-06-30 00:02:05 UTC 
I can still pause a game without starting one, but I can no longer reproduce the crash - but I've gone the the next version of Ubuntu.
Comment 4 Frederik Schwarzer 2011-06-30 00:49:50 UTC 
Ok, thanks, I will change the severity of the bug then.
Comment 5 Julian Helfferich 2015-12-19 19:08:52 UTC 
Git commit 6879ab00fbbda433174bb3fa8b8de8bcc7c950a8 by Julian Helfferich.
Committed on 17/12/2015 at 02:26.
Pushed by helfferich into branch 'master'.

Deactivate pause button when no game is running

Before, the pause button was always activated even when no game was
running. This lead to undesired behavior, e.g. making it necessary to
press the pause button twice to pause the game.

With this fix, the pause button is deactivated on startup. The button
gets activated when a game is started and when the button is pressed, it
checks whether there is a running game.
