Description Clemens Eisserer 2009-08-24 00:55:03 UTC
While resizing dolphin running with QT4's opengl backend, I got this crash.
I am running 2.6.31rc6 + the latest packages shipped by fedora rawhide (2.8.0 + xorg-1.6.99.901).

Program received signal SIGSEGV, Segmentation fault.

Could you do a bit more debugging and determine which pointer might be null or invalid?
