Summary: Morrowind crashes with: filesource.c:1355:
                    FileAsyncReader_EndFlush: Asserzione `!This-
                    >sample_list[x].pSample' fallita.
           Product: Wine
           Version: CVS/GIT
          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: quartz
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I use Wine GIT and I could play Morrowind with wine-1.1.0-253-g2f1c7b1.
A few hours ago I updated my local GIT, recompiled and tried. Morrowind opens
normally, but when I try to load a game, it prints this out

filesource.c:1355: FileAsyncReader_EndFlush: Asserzione
`!This->sample_list[x].pSample' fallita.
(translation, just to be sure: Asserzione -> Assertion; fallita -> failed)

and then crashes (I'm going to attach backtrace). I found 'filesource.c' in
'dlls/quartz/', so I think it should be a quartz regression.

As I said, it worked with wine-1.1.0-253-g2f1c7b1 but not with current GIT
(this is the HEAD:
http://source.winehq.org/git/wine.git/?a=commit;h=2734fb44e0f4065179044b9eb9...).
If I'll have some free time I'll try to identify the commit which caused the
regression, but it should be easy even without my help, considering the [small]
number of patches to check ;)
