Summary: Guildwars crashes with assersion failure
           Product: Wine
           Version: 0.9.30.
          Platform: Other
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-directx-d3d
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Using the opengl backend, Guild Wars crashes (or technically infinately hangs)
with the following:

glx_texture_compression.c:58: __indirect_glGetCompressedTexImageARB: Assertion
`image_bytes >= ((4 * reply.length) - 3)' failed.

This occurs in under two minutes of game play, with both the alpha mouse patch,
and lighting 'fix' applied (without these, the game is unplayable, or crashes
anyway).  This is on an nVidia card;  When played on an laptop with an Intel
card, I have yet to encounter this problem.
