In reply to your request for feedback, I can report the following for an 
AMD 64 PC running Kubuntu 9.10 running KDE 4.3.2. Results are 
interleaved below with with comments and one question.

texdoc debug-version: /usr/local/texlive/2009/bin/x86_64-linux/texdoc 
version 0.61
texdoc debug-view: View comand: (kde-open

In Kubuntu, under

System Settings -> Advanced -> File Associations -> application -> pdf

I have okular as the first viewer.


texdoc texdoc

gives this warning message

<unknown program name>(16501)/ ClientApp::doIt: Creating ClientApp

but correctly shows the texdoc documentation in an okular window. 
Likewise for other packages.
