I am not too familiar with this bug, but I can across a recent patch
[1] to x.org to fix a memory leak in XICreateDeviceProperty(), around
the same lines where this crash is happening.
Error: Memory leak (CWE 401)
Memory leak of pointer 'prop' allocated with XICreateDeviceProperty(property)
at line 774 of Xi/xiproperty.c in function 'XIChangeDeviceProperty'.
'prop' allocated at line 700 with XICreateDeviceProperty(property).
prop leaks when handler != NULL at line 768
and handler->SetProperty != NULL at line 769
and checkonly != 0 at line 772
and rc != 0 at line 772.
The patch is:
