[Bug 22904] New: Register URL protocol handlers under Linux

http://bugs.winehq.org/show_bug.cgi?id=22904

Summary: Register URL protocol handlers under Linux
           Product: Wine
           Version: unspecified
          Platform: All
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: programs
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

winemenubuilder is able to automatically register file type associations and
build menus under Linux, when triggered by an application under wine.

It would be great if the same thing were true for protocol handlers, so that
these would become registered in much the same way as when using gconftool in
gnome:

gconftool -s /desktop/gnome/url-handlers/spotify/command 'wine
c:\spotify\spotify.exe %s' --type String
gconftool-2 -s /desktop/gnome/url-handlers/spotify/enabled --type Boolean true

Would this be possible, hard, or maybe not a good idea?
