trace output - startup to final exit

With World of Warcraft on 1.1.32 (378-g416cd48) the game starts and runs nicely
enough, but upon exiting does one of two things:

a) crashes, creating two crash dialogues and posting a backtrace in the
terminal
or b) X.org spontaneously dies.

This leads me to think there's something broken under the hood of my NVidia
driver in respect to how this new version of Wine is working with it, or
previously stubbed calls between them are resolved, exposing the problem.

Trace attached, please post if you need additional information, along with some
layman instructions on how to get at it.

The '^C' on line 39 of the attachment is me Ctrl-C'ing to induce a kill to exit
the game from the initial login screen (I didn't actually load the "game" part
of the game, just as far as the Username/Password entry screen).

In the trace provided, X.org didn't crash, but World of Warcraft did, so
something went sour either way.
