Is this in reference to the pidgin_notify_uri() function in
pidgin/gtknotify.c?  Have GNOME and KDE always set the appropriate xdg
variables?  If older versions of GNOME did not set them and you remove
the GNOME-specific and KDE-specific code, it seems like it would harm
any users who may be using those older versions.

And it's not clear to me how removing that code would help people not
using kde/gnome... we already attempt to use xdg-open, don't we?
Could you explain?
