I removed the libfacebook.so (i.e. the 1.63 version from the devel repository), since it made the Facebook contacts appear as their Facebook ID's and not their names. So, I'm using the 1.64 version downloaded from the pidgin-facebookchat web site. I also did apt-get update and apt-get upgrade, which updated a bunch of packages (although App Manager told me there was nothing to upgrade). Among the packages were a couple of Telepathy and Haze related ones. After a reboot, I rerereremerged a couple of Facebook contacts, and rebooted again. They're still merged. So hopefully the merging problem is solved.

The apt-get upgrade also solved ICQ (haven't been online for a couple of weeks) and YIM/AIM problems ("network error", requiring reboot to get online).

There's still some problem. Going Availability -> Facebook -> Advanced settings show up an empty tab. To get to the advanced settings, I have to disable the account and then go Availability -> Accounts -> Facebook -> Advanced settings. And if I change anything, the changes don't stick when I save them. Going there again, even if going all the way out first, shows the same settings as before I changed something. I think it's because my guess about the settings syntax was wrong (see http://talk.maemo.org/showthread.php?t=39331&page=3#26 ). I'll change that, and see if it makes any difference.

MySpace: Still noone to talk to. Anyone here having a MySpace account, so I can test it?

Nathanielsametz: I don't know how to make packages and upload them to the repository. I might look into it though, or ask the pidgin-facebookchat-packager to package a conversation/contacts version too.
