mailto and galeon?

[Martin Klaffenboeck <martin klaffenboeck gmx at>]

Hello,

I'd like to send mails via balsa2 from galeon2  But when I click on a 
mailto link in galeon, I get the message: Galeon cannot handle this 
protocol, and no GNOME default handler is set.

Where can I set this default handler in gnome2 and how must this 
handler look like?

Thanks,
Martin
