Comment 68 for bug 552227

Using an up-to-date Lucid with gwibber 2.30.0.1-0ubuntu1, I have the same problem: I authenticate on facebook but cannot add. Tried the patch from Toby Roworth (post #64) and got exactly the same error message as Jorge Rubio on post #67.

Since some people had success with OpenDNS (not my case), this error might have something to do with language settings; my system is configured for pt-BR, a language supported by facebook. The facebook login page within gwibber is presented in pt-BR. I was unable to make the facebook page come up in English. If someone knows how to do it, I may try to see if the behaviour changes.

What I already tried: I tried unsetting LANG, LANGUAGE and LC_ALL before running gwibber (the UI was presented in English, but not the Facebook page), tried to activate a proxy on gnome preferences and on firefox to go through a us-based proxy (not sure it worked, though), changed DNS servers to OpenDNS, and tried to change the preferred languages order in firefox (is firefox the embedded browser?).
