It was already reported upstream, so I "fixed" it by putting gnome-open
etc at the end of the list in a later texdoc version. This should make
the viewer selection no worse than it was before I added those, but
won't recognize kde/gnome/whatever properly.

However, see below.

This is a good suggestion. I may try to enhance the viewer selection in
future versions by looking at those variables also. Do you have a
pointer to this in the KDE documentation?

In the meanwhile, you can still select your prefered viewer in your
local configuration file.

Ok. I can provide you with a patch against 0.47 so that gnome-open etc
come at the end of the list, which is done in current versions of texdoc.
Or you can update texdoc from current TL. Or whatever you suggest.
