There are several places this function is called with a NULL event pointer
including lib/Xm/Primitive.c (_PrimitiveTrait_Redraw) line 1558. The
attached trivial patch prevents a core dump in these cases. Based upon
the comment above this change, I doubt this line of code should even be
there.
Please CC me on responses as I am not subscribed to the list. Thank you.
