I'm using Gaim v0.68 with the v2.10 plugin on Windows.
One system is Xp sp1, the other system is Xp sp1
with a 4096 bit key on both Gaim clients, successful
key negotation takes place, but every time one client
transmits a encrypted message to the other client, the
receiving client crashes. Backing off to a 2048 bit
key works just fine.
