I just had a go with the latest (10.09.2013) raspian and did a fresh install.
Installed Synaptic, but ran across an error message when launching it. "pango-warning"....
So I did some googling and found that this was experienced on other linux platforms as well, among non-english users.
It seems that synaptic have a problem with some of the norwegian localization, and also some other languages.
The workaround is to launch synaptic with the following command:
sudo LANG=en_GB.UTF8 synaptic
I did make a small script with that command and placed it on my desktop for easy access.
