“Yesterday [15.8.2006], Gaim started crashing for a bunch of people (most notably Windows users) when trying to connect a MSN account. […]
Gaim 2.0.0beta3.1 has been released which fixes this and other bugs in beta3. You can download it from its SourceForge file release page.”
I’ve been suffering from this too. There was one day since the problem began, when I was able to login to MSN using Gaim, but thereafter it’s been crashing each time again.
Just tried the new Beta, and it does fix this as promised.
