I'm a fedora users too, and I think that it's crazy that a great software like kopete can't inherit the proxy settings from kcontrol, using Dante + Tor is a option, but this is crazy too, like using a katana to cut a banana :-).
Form my point of view this this is an important bug to fix, kopete can connect thorught different protocol till you don't have a proxy in your lan.
Thanks for your work
Cheers
