Yes, I knew this, that ist why I looked into the GDB where the server was
hanging. I am not experienced with X debugging to understand this bug though,
so I decided to ask here.

> Much more interesting is this backtrace:

It looks to me that the server causes an deadlock in the kernel, and after that
it hopelessly hangs in that tight loop trying to get a response from the
kernel....
