Well, the most well eve known bug in aMule v2-rcX is... that it crashes after X hours :-D
But that's not useful to us, of course.
If you want to help us, you'll have to report a backtrace. Please come into #amule in irc.freenode.net and I'll guide you into compiling aMule in Debian Sid.
I'm waiting for you in #amule ! ;-)
Greetings.
