It's normal with +snoop. Snooping is implemented by pure heuristics, if it hurts - don't do that. Neither +all nor +snoop are useful for wine debugging.
I <i>guarantee</i> that "+all" is often critical for my particular use of wine, but now that I know that +snoop crash, I will certainly avoid it.
The fact that +snoop hasn't crashed on me before (nor in the last three years' worth of using Wine that I can ever remember), this suggests to me that it's a newly created crash and something that would be of concern to anyone that continues to actually want to trace snoop.
I personally would not consider +snoop crashes to be "normal".
