[Wine] Sims 3 crashes while loading town (Bug 18991)

[missouri2006]

Hey you guys,
ok I have been trying to get The Sims 3 base game running on my Lenovo L512 on Ubuntu 10.04 for several months now and I just don't seem to be successful. So I was hoping, maybe you can help me out on this one:

I installed it using PlayOnLinux (v. 3.8.8) which installs Wine 1.3.4, I run the game on Wine 1.2.1 (since thats the working Version, see here: http://appdb.winehq.org/objectManager.php?sClass=version&iId=16664&iTestingId=58209). I followed all the steps from here: http://www.playonlinux.com/en/topic-2530-Solutions_for_frequent_problems.html.

Everything went well with the installation but whenever loading a town the game crashes to the desktop after loading like 1/6 of the bar. The bug is known and reported here: http://bugs.winehq.org/show_bug.cgi?id=18991.
I ran the fixtz.exe from the bugreport to fix the Mono timezone bug and nothing changed.

Can you help me out here?
Thanks a lot
Dominik
