A workaround is to execute
 unset http_proxy
before executing apt-get or synaptic from a terminal or putting this at the
end of your ~/.bashrc (or a equivalent if you're using another login shell)

I meant the gnome terminal but the next thing to try would have been a
tty :-)

Did you try to log out and log in again (check the proxy settings after
log in)?
Create a new user. Has he http_proxy set?

Some kind of last resort:
Does
 grep -R /etc
or
 grep -R $HOME
find anything (the latter one will take much time)?
