I cannot start a group chat or enter a group chat using MSN on Kopete. 

There are no errors reported or crashes, it just doesn't work. In the case of being invited into an already existing group chat, Kopete notifies me of the group chat (by the spinning icon in the system tray) but I cannot enter the chat. I've tried opening windows to the recipients individually and it starts a separate discussion and doesn't join me to the chat.

This had worked flawlessly on KDE 3.5.9 and previous 3.x versions.

Steps to Replicate (for starting group chat):

1. Open a chat window to a contact in MSN
2. Attempt to invite another MSN contact
3. Fail..nothing happens.

Steps to Replicate (for being invited into a group chat):
1. Have a contact start a group chat.
2. Ask contact to invite you into group chat
3. Kopete notifies of invitation by swirling icon in tray but cannot join.
