[Wine] Help needed troubleshooting page fault in wine

[dk]

I'm trying to troubleshoot  a game crash under Wine. Here's a snippet from the log file created under Wine 1.3.20:


Code:
wine: Unhandled page fault on read access to 0x00000000 at address 0x44a179 (thread 0022), starting debugger...
Unhandled exception: page fault on read access to 0x00000000 in 32-bit code (0x0044a179).

Backtrace:

I don't have a clue what is causing the crash. With the above information is there anything I can do to determine if this is an issue with Wine? I just did a fresh install of the new Ubuntu (64 bit) release last week so I have a relatively clean environment. It might be distro related but honestly I can't tell either way at this point.

Can anyone tell me what's happening at 0x0044a179?
