Thanks for your detailed test and the added information. I didn't managed to test/debug the problem yet, sorry for this.
It seems like there is a bug in gksu somehow because gksu should export the current gconf proxy information to the applications started via gksu. So if synaptic is started from the system menu, the http_proxy information should be set in the environment of synaptic. I don't know (currently) why this dosn't work for you.
