Hi everyone, attaching backtrace as instructed.
Amule works correctly for some time (say, in the order of half an hour, maybe an hour).
Apparently no problem, then silently crashes without user interaction.
Working on debian testing with kernel 4.6.0-1-amd64, installed from deb-multimedia repositories
(originally worked, by originally I mean plenty of dist-upgrades ago)
Thanks, all the best
