I've got many protocols im, and msn inside, so crashes after crashes, I wanted to have something working.
So I took Adium 0.87, and since this morning, Adium didn't crash yet
It's just a repairing solution, but I don't know if I'm right to do so or not (security, stability, etc...)
PS : I didn't try the 1.0beta version, I don't know where to download it
