Upgrade to 10.5.4 loses contacts' aliuses

[WinterPhoenix]

I just upgraded to 10.5.4 a few minutes ago. Upon restarting and loading adium, I realized that almost all of the aliuses I associated with my contacts on my buddy list had disappeared. Not all were lost, however. The ones that I've added over the past... two weeks or so have remained. I know that it happened from the upgrade because immediately prior to restarting I was on Adium and the aliuses were in tact. It doesn't seem like a random error either, my friend mentioned the same problem when I asked him about it.

This happened on a Rev. A MacBook Pro and Adium 1.2.5. All the contacts on my buddy list and the only account I have registered with Adium are AIM members
