Comment 76 for bug 348332

I got a freeze again, so option 4) ist definitely not true.

Furthermore Composite is still disabled so this is not a workaround for the problem.

The hang occured when many applications were open and this time I did not have any Kopete Chat Windows opened (although kopete itself was running).

Just before X freezes the mouse-cursor gets damaged and a few seconds later everything gets real slow.

I than logged via ssh into the defect machine and attached gdb to the process. I append the output of "bt f", hope thats helpful.
