Threading issue with dinput/joysticks

[d13f00l]

http://veracity.ath.cx/~diefool/failure.gz  Log is about 100 megs unzipped.

This is pretty bizzare.  I gzipped a +all log.  When a joystick is plugged
into my machine, many dinput apps crash with meaningless backtraces
unrelated to dinput.

It affects a fair amount of apps
http://www.blockland.us/blockland/index.asp is an easy one to work on since
it crashes as soon as the program starts.  It also only crashes when my
joystick is plugged in and wine can see /dev/js0.

I think this is where it gives up in the log. ^^

I'd like to debug this, anyone know where to start?
