Thanks, it's indeed a problem in Xlib. I already tested the patch from 
Daniel but was still getting segmentation faults and sequence lost 
errors when testing with "xinput test-xi2" for example. However, the 
patch from Daniel certainly helps me to avoid the original crashes that 
I had. Unfortunately I haven't currently had time to investigate the 
remaining problems further.
