Comment 1 Marco Carrai 2010-06-29 19:31:14 UTC 
Still happens on RC1
Comment 2 alpha1beta 2010-07-25 04:22:44 UTC 
I can confirm this bug. Its a guaranteed crash. Really needs to get fixed.
Comment 3 Hugo Pereira Da Costa 2010-07-25 04:42:00 UTC 
seems Aurorae related. Martin ? Any clue ? 
I can't reproduce here.
Could it be cause to an ill-formed aurorae theme ?
Comment 4 alpha1beta 2010-07-25 05:24:41 UTC 
@Hugo Could be, I had Kde4-winwindeco-aurorae installed, but It was not in use when It crashed. I was using Bespin.
Comment 5 Hugo Pereira Da Costa 2010-07-25 05:29:46 UTC 
I meant: ill formed in the sense that it makes the _preview_ crash (which seems to be the case here). This disregarding whether it is actually used or not. (hope it makes sense).
Comment 6 Martin Flöser 2010-07-25 08:18:57 UTC 
> seems Aurorae related. Martin ? Any clue ?
No not yet
> I can't reproduce here.
Me neither, but I get the same crash in AuroraeDesigner, though the source 
code there is not up to date.
> Could it be cause to an ill-formed aurorae theme ?
Possibly, but it would not explain why I get it in AuroraeDesigner and not in 
the kcm.

> I meant: ill formed in the sense that it makes the

Yes, exactly that seems to be the case. I just was able to untrigger the crash 
in AuroraeDesigner by testing m_theme->isValid(). Let's see that should give a 
hint on how to fix that crash
Comment 8 Martin Flöser 2010-07-25 09:03:38 UTC 
By adding some debug statements, I found:
* Theme  "radial"  is not valid - skipping
* Theme  "win7-deco"  is not valid - skipping

But I still have no idea why those themes work for me in systemsettings

Proposed patch

Could anyone experiencing this crash test this patch? I am still unable to reproduce the crash in systemsettings, but from the fix I wrote for AuroraeDesigner I am pretty sure that this patch will work. Nevertheless I would like to have it tested one week before release tagging.
Comment 10 Marco Carrai 2010-07-26 20:36:40 UTC 
Can't test, not using sources:( Still happens on 4.4.93..
Comment 11 Martin Flöser 2010-07-26 23:13:03 UTC 
> Can't test, not using sources:( Still happens on 4.4.93..
And if nobody is
able to test the patch, it will also happen in 4.5.0 as I won't ship an
untested patch a few days before release tagging.

Up to now, I would
recommend to remove some themes form ~/.kde[4]+/share/apps/aurorae/themes -
the crash is most likely caused by one of them. If you are able to identify
the theme causing the crash, please name it here.
