Jan-Philipp Litza: Thanks a lot for the fix which works perfectly! Let me just mention that it's quite difficult for unexperienced users to download the archive and unzip it on the n900. I recommend a easier way:
- Open Xterm and become root
- cd /opt/zoutube/
- cp zoutube zoutube.bak
- wget http://github.com/deadorc/zoutube/raw/master/zoutube
- chmod a+x zoutube
The last command is important otherwise zoutube can not be started.
Thanks again for the nice work!

I tried the fix suggested by Michael Rosch above, I used the rootsh download as I have no idea how to "become root" in Xterm or anything else for that matter and it seemed to work. Everything seemed to be fine until I tried teh "wget" command but this came back with "wget not found". Can someplease suggest a solution to this as I would like to be able to use Zoutube. Thanks, osi.
