No glue, how long this "bug" exist, but yesterday an icq contact send me an message. I want reply but can't send the message - I see only the progress sign. Google tells me that: http://forum.ubuntuusers.de/topic/kopet ... st-4377632

Summary: If u send a message with pidgin, u get an system message from icq with an reactivation link. After clicking and reactivation all work again. Why Kopete doesn't show this server message? It looks like icq want kick inactive accounts in the future.

System / Service messages are usually shown in the main window of Kopete - the same one that lists all of your contacts. You may need to click the blue flag to show them if they are not showing however.
