Log of crash playing WoW

Installed 1.1.21 on 32-bit Ubuntu 9.04 following the directions on the Winehq
site and did not encounter an error.  However, I'm getting the following
intermittent error trying to play WoW:

err:heap:HEAP_ValidateInUseArena Heap 0x110000: in-use arena 0x1945d020 next
block has PREV_FREE flag
wine: Unhandled page fault on write access to 0x39c6528d at address 0x7bc45544
(thread 0009), starting debugger...
err:heap:HEAP_ValidateInUseArena Heap 0x110000: bad back ptr 0x18805a09 for
arena 0x1945d068
err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr
0x7bc45544

Attached is the complete log until the crash.  Also attached is my dmesg.

Note that WoW installed and updated perfectly with no crashes at all.  I'm only
getting this crash when playing the game.
