It could be related with, https://bugs.freedesktop.org/show_bug.cgi?id=36738 , which I don't have much clue about ,given I wasn't able to reproduce locally so far.
It would be really useful if you could tell me the nature of the crash. Is it because - memory pointed by (esi+ebx) is undefined; - memory pointed by (esi+ebx) is not 4-byte aligned And then go up in the stack frame and inspect the pointers given in draw->pt.user and see which pointer (if any) is related with (esi+ebx).
