Gajim isn't displaying nicknames of transports in PM
problem
Same nickname with every transport (AIM, ICQ, IRC, Identi.ca/StatusNet and any other transport).
analysis
In case my Jabber nickname is X and my IRC nickname is Y, Gajim will display X instead of Y in direct/personal/private (one on one) chats.
For the record: Gajim respects IRC nicknames in public chats.
enhancement recommendation
Add to Gajim the ability to respect these nicknames in one-on-one chats as well.
