upps wrong version - it's KDE 4.00.81

I couldn't reproduce this crash with a fresh revision (kdebase rev. 817679). I tried clicking on every item then on the overview button without getting any result.

Can you reproduce it ? Could you give more details (eg. what were you doing just before)

The backtrace seems close to bug #163078

You are right - and thx for bug #163078 - I'm able to reproduce it...

Click "Regional and Language" => choose "Skip all uppercase words" => Click "Overview" => apply to save changes => crash

So this bug-report seems to be duplicated! Please merge it with 163078...

here is an additional backtrace:
