Comment 2 for bug 116804

csdemo comes from the crystalspace package and the data needed for this demo comes from crystalspace-data.
However, crystalspace-data is out of date (0.98) so the csdemo.zip file is out of date if you install it without any further checking.

If you combine these two versions running csdemo with that zip file will create the following error:
$ csdemo /usr/lib/crystalspace/data/demodata.zip

Trying to find a new demodata.zip on the internet won't work. When going on IRC the following was responded:
<bmm> Hi everybody. Where can I find demodata.zip for csdemo from CS 1.0 ?
<thebolt|work> bmm: nowhere
<thebolt|work> use walktest instead of csdemo
<bmm> thebolt|work Ok, thanks

So csdemo will probably never work. I could not get walktest running correctly, but that is another bug/problem.
