I feared you would say that :)
The problem is: I've run gdb in the kernel build directory but it seems gdb 
really can't find the source for this memory address. If I use the memory 
address below the problematic line in the xenctx call trace (ffffffff811e4a2e) 
I get code from gdb...
But maybe it's just my fault - I'm really no expert in debuggers in common or 
gdb in special ;)

Markus
