Well, yes. I also cleard the horde cache:
rm -v /kolab/var/kolab/webclient_data/tmp/cache_*

The weird part is that it actually worked, but now preview is disabled  
again. I can't remember exactly what I did and when it stopped working. I  
only remember running kolabconf after changing some settings back the  
default.

I'll try to backtrack. Can someone answer me if this is the usual course  
of action to fix this?
- dpgk-reconfigure locales (choose some .UTF-8 locales, choose a default,  
like en_US.UTF-8)
- rm -v /kolab/var/kolab/webclient_data/tmp/cache_*
- /kolab/bin/openpkg rc apache restart
