Crash in KScoreDialog

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):

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.

Sure, I'll take a look. It shouldn't be anything too hard to
find. However, 
I'm pretty busy with exams at the moment so it'll be about a
week before I 
have time.

Great! That's not a major crash, so I think it can wait
untill you'll be 
free .

Good luck with your exams, Matt!

Dmitry.
