Comment 6 for bug 65580

I left the original modifications in xchat.c as I wasn't sure what they actually did -- I just altered the existing debian patch.

2 is indeed broken. I don't have a KDE install to test it with however.

xdg-open is part of the Portland project

http://portland.freedesktop.org/xdg-utils-1.0beta1/xdg-open.html

the idea being that it takes care of all this sort of thing so the application dosen't have to worry about what the users preferred browser is without being tied to a single desktop environments settings / API. It would be a sensible inclusion upstream I think :)
