Comment 13 for bug 938667

I noticed services were not from branch in my previous test, so i removed every gwibber package and then explicitly installed 3.4.1-0ubuntu1.1 from precise-proposed:
stefan@***:~$ sudo aptitude install gwibber-service/precise-proposed gwibber/precise-proposed libgwibber2/precise-proposed libgwibber-gtk2/precise-proposed gwibber-service-facebook/precise-proposed gwibber-service-identica/precise-proposed gwibber-service-twitter/precise-proposed
The following NEW packages will be installed:
  gwibber gwibber-service gwibber-service-facebook gwibber-service-identica
  gwibber-service-twitter libgwibber-gtk2 libgwibber2
