Summary: gamestop downloader crashes in
                    is_preserving_whitespace in xmlParseCharData
           Product: Wine
           Version: 1.3.9
          Platform: x86
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: msxml3
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I tried downloading a game purchased from gamestop's web site, 
without much luck.  The download manager failed with

err:msxml:doparse XML declaration allowed only at the start of the document
wine: Unhandled page fault on read access to 0x00000020 at address 0x7db96fc6
(thread 003e), starting debugger...

This is on gentoo, with libxml2-2.7.3-r2.  (There's a 2.7.6 available.)

I would have tried native msxml3, but bug 25517 interfered...
