Summary: Steam causes Xorg to exit, new to wine 1.1.43
           Product: Wine
           Version: 1.1.43
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Running steam (after the 26th April update) on wine 1.1.43 causes Xorg to exit.
 Sometimes the outline of the GUI has time to appear, sometimes not.

Reverting to wine 1.1.42 avoids the problem, and steam appears to work fine.

The only error message in /var/log/Xorg.0.log.old is:

Backtrace:
0: /usr/bin/X(xorg_backtrace+0x3b) [0x8133d6b]
1: /usr/bin/X(xf86SigHandler+0x55) [0x80c7d35]
2: [0xe91400]
Saw signal 11.  Server aborting.

This is on Ubuntu 9.10 with NVIDA driver version 185.18.36.
