[Bug 25620] New: winememubuilder keeps adding the same associations for Nautilus

http://bugs.winehq.org/show_bug.cgi?id=25620

Summary: winememubuilder keeps adding the same associations for
                    Nautilus
           Product: Wine
           Version: 1.3.10
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I am testing with installing applications on an Ubuntu machine.
To remove the application, I remove the ~/.wine directory.

However, re-installing for example the office suite, duplicates all file
association entries in Nautilus each time.
Thus, in the Nautilus "open with" menu I now have 10 times the same excel
application.
Can winemenubuilder check if an entry is already present, and not add the next,
same, entry ?
