http://bugs.winehq.org/show_bug.cgi?id=24233

Summary: MS Paint uses garbage instead of "untitled" as the
                    default file name
           Product: Wine
           Version: 1.3.1
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: msvcrt
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
                CC: [e-mail]

Steps to reproduce:

1. Install with 'winetricks mspaint'
2. Run 'wine mspaint'
3. Click file -> save as...

expected "untitled". In 1.3.1, it was displayed correctly. My regression test

Reverting that patch makes the problem go away. The program doesn't generate
any terminal output.
