That's not helpful. If you want bugs fixed, then file bug reports, preferably, the a debug log. Regarding the issue at hand, it looks like the problem is in telepathy-haze (also used by msn-pecan internally), and is related to PR1.2, but perhaps it's only reproducible by flashing, not by updating over the air.
I'm using also Butterfly now and got no issues on 1.2, its only quite "primitive" so it doesn't sends a avatar and stuff. Also the IM logging works fine.
