Just to let you know I tried all the info above and nothing worked...
BTW -- I'm running Gwibber 220.127.116.11 on Ubuntu 10.04 LTS
Then I remember the hack I had to do in order to have Twitter working -- increase the timeouts in /usr/share/pyshared/gwibber/microblog/network.py
So, I did the same to the /usr/share/pyshared/gwibber/microblog/util/facelib.py
c.setopt(pycurl.TIMEOUT, 15) ## 15 secs only?
c.setopt(pycurl.CONNECTTIMEOUT, 8) ## 8 secs? really?? you guys have an insanely fast connection :)
I know this timeout is much bigger now, but at least things work perfectly -- both Facebook & Twitter.
