0.start a xfce session
1.set another browser than firefox as the default
2.wipe the thunderbird settings

Additional info:
not a new bug :
https://bugzilla.redhat.com/show_bug.cgi?id=557599 (fedora 12)

a workaround is to install gconf-editor and edit entries of /desktop/gnome/url-handlers/http and related from "firefox %s" to "xdg-open %s"
