Summary: crash when running Shake 2.4 and workaround
           Product: Wine
           Version: 20020904
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-x11driver
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I'm running NothingReal's (now apple's) Shake 2.4 under wine 20021007.  I can
cause a crash by launching shake, creating a "colorcorrect" node (under the
"color" tab bottom left), and then clicking on the "curves" tab near the bottom
right of the screen.  The crash occurs in graphics/x11drv/dib.c in
X11DRV_DIB_Convert_888_to_0888_asis().  As a workaround, if I add code at the
beginning of that function to return if srclinebytes  < 0, then everything works
fine.
