Do you think you could reproduce the crash ? Thanks

I have reproduced it 4.3 RC 2. My steps are:

1. Open 'System settings'.

2. Select 'Keyboard and mouse'.

3. Select 'Standart keyboard shortcuts'.

4. Press 'Overview' (back) button.

It craches with 100% success on my desktop.

With the steps described at comment 2 I could reproduce the crash but I'm getting a different backtrace, so I think it could be a different crash. I have opened a new report about it: bug 200665.
Thanks

I'm now using KDE 4.3 RC2. I could reproduce the bug with those steps, the backtrace seems similar to the original one I reported:

Very interesting since this only happens with the Standard Keyboard Shortcuts module, and only when using the Icons View and the module hasn't been focused.
