Comment 18 for bug 515386

Unfortunately, this fix does not work anymore with thunderbird 3, because of two regressions in the way thunderbird 3 handle -compose. I've reported the issue in thunderbird bugzilla and all details about this problem can be found here :

I guess that this has to be fixed in thunderbird and not xdg-utils, but I might be wrong.
