[Kde-games-devel] Crash in KScoreDialog

[Dmitry Suzdalev]

Hello!

While writing most recent fix for katomic, I catched a crash in KScoreDialog.

Unfortunately I can't call this crash 100% reproducible. I tried several 
times. It happens _sometimes_ after I complete the level, enter my name in 
KScoreDialog and hit "OK". Good news is that I have a backtrace :-). Here it 
is (I guess #8 is of interest):

#3  0xb5e52fb9 in abort () from /lib/tls/i686/cmov/libc.so.6

Btw, while playing katomic I repeatedly see this debug output (maybe it'll be 
of some help?):

libkdegames (Highscores): The current high score group "Highscores Level 3" 
isn't in the list, adding it
libkdegames (Highscores): The current high score group "Highscores Level 4" 
isn't in the list, adding it
libkdegames (Highscores): Removing group "Highscores Level 4" since it's 
unused.
libkdegames (Highscores): The current high score group "Highscores Level 4" 
isn't in the list, adding it
libkdegames (Highscores): Removing group "Highscores Level 4" since it's 
unused.
etc etc...

Sorry, currently I lack motivation to fix that myself :). Hope that someone 
(Matt?) will look into it.

Cheers,
Dmitry.
