Contacts with no name

[newtonuk]

I'm running the latest public release of Adium and OS X 10.5.2.

I also have my contact list linked to my Address Book so that it shows the correctly formatted names instead of MSN IDs.

However, I have two MSN contacts whose names only show as blank. I can add their names in the Alias field in properties, but when I restart Adium they show as blank again.

When I turn the link to the Address Book off the names show as the alias correctly.

Any thoughts?
