[KDE4] Bug in khtml::RenderObject::markedForRepaint

[Mathias Soeken]

Hi,

kmail crashes, if I start it (or clicking on Local folders). I think this 
error exists for some time but I never cared, because the rendering widget 
was not shown in kate until now, so that the krash occurs at startup.

So, the error seems to be based on the rendering widget, this crash was 
produced by revision 640594. I also reverted to 637017, but nothing changes. 
As I said, I think, this error is exisiting for some time.

Best regards,
Mathias
