I have a (i think) similiar problem.

Don't know how to explain it properly so i use an example:

In Conversations I open a saved Conversation from ICQ, the task says "Chat-Sarah". Now when i'm in a conversation (ICQ running) it just says "Chat-84...( the Contacts ICQ number).

So when i have multiple chats running i can't see which task belongs to which Contact from the Dashboard.

Choosing Nicknames first in Contact List didn't help.
