In version 0.7.0 of ktelepathy the log viewer shows only ICQ numbers instead of the full name in the list on the left. I expect to see the name because I don't know every ICQ number of my contacts.
Do you use KPeople (Nepomuk)? Is the ICQ account active/online?
(In reply to comment #1) > Do you use KPeople (Nepomuk)? Is the ICQ account active/online? Of course, kpeople 0.1.0 ist installed and Nepomuk is running. And yes, all my accounts (ICQ included) are only. As additional information: the Plasmoid which shows me my instant messaging contacts is working correctly. All ICQ and XMPP contacts are displayed with full name. I'll try to reinstall all relevant packages and maybe delete my config.
Ok, I figured out that reinstalling ktelepathy (and the kpeople lib) and restarting the KDE desktop solved the problem. I can't say what the problem actually was because I don't the internal mechanisms of ktelepathy and nepomuk.
