Bug 240571

Application: konqueror (4.4.2 (KDE 4.4.2))
KDE Platform Version: 4.4.2 (KDE 4.4.2)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-22-generic x86_64
Distribution: Ubuntu 10.04 LTS

-- Information about the crash:
Using the awesome wm (a tiling window manager) under a 2 screen setup. Changing the wm-layout with awesome (Mod+Space) serveral times results in extensive resizing of the running X-programs. In this case several open windows of konqueror. This leads to this segfault of konqueror.

 -- Backtrace:
Application: Konqueror (konqueror), signal: Segmentation fault
