I am running Ubuntu, Peppermint 7.
Amule kept crashing consistently until I removed the latest ipfilter from eMule Security -http://www.emule-security.org/news.php
Once the URL was removed from Preferences > Security, aMule has been stable.
But - now I don't have an ipfilter.
I suppose I can live without it, but it's like going commando again.
