this is a very reproductible problem.
i can make amirc crash very easly.
it just need to download large files often, and being online for one day (sometimes less),
and you're sure to crash it.

i don't know if the problem come from often downloading files or from colorful personnal settings or whatever, but it's there.
thoses who say that amirc don't crash: they're simply don't use it enough, on time basis, and with lots of downloads..
