Several days ago my ICQ account stopped working with kopete (0.12.3). Jabber/Google talk was working ok. I tried to login with Licq, and there were no any problem. So it looked like it had something to do with Kopete and its icq plugin.
Since its worked ok i suppose there were some changes made to ICQ protocol. I wonder how licq can work still. Anyway, there's a patch already available. To fix this issue with ICQ one needs to do the following in Ubuntu:
$ mkdir /tmp/kopete $ cd /tmp/kopete $ wget http://librarian.launchpad.net/4945802/kopete_fix_kopete0.12.3-0ubuntu1_to_kopete0.12.3-0ubuntu3.debdiff $ apt-get source kopete $ cd kopete-3.5.5+kopete0.12.3 $ patch -p1 < ../kopete_fix_kopete0.12.3-0ubuntu1_to_kopete0.12.3-0ubuntu3.debdiff $ dpkg-buildpackage -uc -us -rfakeroot $ dpkg -i ../kopete_3.5.5+kopete0.12.3-0ubuntu3_i386.deb
