This is actually gconf, not Meld. Meld *also* has dbus support, but
that should fail gracefully if we can't connect. We also have a
fallback for gconf support, but right now it only works if you don't
have gconf installed; if it's installed but can't connect, then it
blows up as above.

It probably wouldn't be too hard to make that fallback depend on
actual gconf viability rather than presence, but I haven't really
looked into it.

OK, thanks.
You want me to open a BZ?
