Thanks. At the time, I temporarily stopped it by disabling my MSN IM account. A few days later, it seemed OK, so I'm not sure if it was something temporary; there seemed to be a number of complaints around the time about Pidgin and MSN, and I wondered if twitter-haze shared any of the same code. I haven't had any issues so far with PR 1.2 as you have.
Cheers, Tony.
