Affects: xchat (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
After an upgrade from Breezy to Dapper, all xchat preferences (i.e.,
channels I log into regularly, identity/nick, etc) were lost. Upon
invoking xchat for the first time after upgrade, I got the "since this
is the first time you have used xchat,..." set up stuff.

Seems to me that we should remember user configs/preferences through an
upgrade.
