When I look at the msn-pecan app in application manager, it is still in the Extras-devel catalog, so it still might be quite buggy as you have experienced first hand. I don't know how long it's been there really, but is that the only msn protocol plugin you can use? Maybe you can try another one to see if it works better, since it seems like there are a couple of them. Tell us which works best if you do try them.
