Bug #: 31814
           Summary: Gecko should clean up when upgrading
           Product: Wine-gecko
           Version: unspecified
          Platform: x86-64
        OS/Version: Linux
            Status: NEW
          Keywords: download, source
          Severity: enhancement
          Priority: P5
         Component: wine-gecko-unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
    Classification: Unclassified

As you move from one version of Gecko to another (by upgrading Wine), the
number of times Gecko is installed increases. Gecko should remove the old
versions if they are no longer needed.

$ rm -rf ~/.wine ; wine-git wineboot ; du -s ~/.wine
234680    /home/test/.wine

$ rm -rf ~/.wine ; wine-1.1.25 wineboot ; sleep 4s ; wine-1.2.3 wineboot ;
sleep 4s ; wine-1.3.20 wineboot ; sleep 4s ; wine-1.5.6 wineboot ; sleep 4s ;
wine-1.5.12 wineboot ; sleep 4s ; du -s ~/.wine
369400    /home/test/.wine

At the moment the amount of additional disk space isn't enormous, but if
multiple users are updating Wine on the same machine the amount of disc space
used can increase dramatically.

The uninstall from the Control Panel just removes the listing, it doesn't
actually delete any files.

In real world use I don't think people will be updating in the fashion shown
above, but it may be something worth thinking about.
