Log: mohaa hang and crash

This is a follow up of Bug 31730

1. Download the Mohaa demo from
http://compactiongames.about.com/od/demos/p/mohaa.htm

4a0c431ed52c4c340b9c883ef859f1d3e7e4ab2e  mohaaspdemo.exe

2. install the demo

3. Ctrl+Alt+F1, switch to the text console

4. export MESA_EXTENSION_MAX_YEAR=2003 , work around Bug 31730

5. start the demo with winedbg
$ export DISPLAY=:0.0
$ cd ~/.wine/drive_c/Program Files/EA\ GAMES/MOHAADemo$
$ winedbg MOHAADemo.exe

type 'c' to continue

The above steps is the only way I found to get the backtrace without any helper
machine. (I don't have helper machine to ssh to my testing machine right now)

Actual result:
- The app crash once I type 'Ctrl+Alt+F7' to switch back to GUI.
- The desktop hangs, mouse can move but clicking doesn't work, "alt+tab" can
call out the switching dock but switching doesn't work.
- after `wineserver -k`, the desktop get normal again, expect the screen
resolution which still stay at 800X600.

Backtrace:
