Crash log without winedebug

GOG.com version of "The Witcher:Enhanced Edition" crashes to desktop when
trying to exit the Mage's Tower in the swamp in the end of the second chapter.

I am using wine 1.5.21 installed from the wine Launchpad PPA.

I am running Ubuntu Desktop 12.10 64-bit with Linux 3.7.0-7. I use the
following command to launch The Witcher:

env WINEPREFIX=~/.wine-test/witcher wine launcher.exe

The prefix that I use has WINEARCH set to "win32" and has d3dx9_36, d3dx9_43
and vcrun2005 installed from winetricks.
