Summary: Warcraft III installer crashes
           Product: Wine
           Version: 0.9.3.
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-x11driver
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

The installer for latest release of Warcraft III RoC released recently in Poland
(as a part of "Platinium Collection"; also includes Frozen Throne) displays
following error box:
Screen Stack :: realize(): BitBlt 2
The installer window is also displayed, but the game cannot be installed,
because the installer exits after clicking "OK" in the error box.
Following error messages are also displayed on the text console:
fixme:bitblt:X11DRV_BitBlt potential optimization - client-side DIB copy
fixme:bitblt:X11DRV_BitBlt potential optimization - client-side DIB copy

This problem can also be reproduced with wine 0.9.1 and 0.9.2 (I didn't check
with earlier releases).
