Here is a special version Kalender4-Test which uses a special directory 
for its calendar data and should run on other systems too.

You need the archive and the kaltes.tar.gz of the special directory. 
Unpack or copy the latter to your $home as $home/.kalendertest/... It 
contains only holiday data, everything else is left out, but it runs 
this way and maybe shows the problem.

Hope this helps!

Rolf
