After fresh FC1 install i've installed mozilla-firebird. In gnome-default-applications-properties i've set the option "user defined webbrowser" to "mozilla-firebird %s". All working fine. After some reboots i noticed that mozilla where used to open an url from evolution instead of firebird. I set up the default application again. It switched back to "mozilla %s" ever. I've tried to use gconf, same effect. What's happend? Open gnome-default-applications-properties from terminal brings no debug output. Any ideas to debug this thing? Schlueri
