I'm reporting on an Assertion failed crash of aMule version 2.4.0~git20151120.0023527bc2-1 (from Debian Sid). No specific circumstances seem to trigger that crash, it just happens during normal operation without any user interaction, sometimes after less than one hour, sometimes after several days.
I'm experiencing these type of crashes already during several recent versions. Does the popping up of a GTK dialog (allowing to stop/continue and to save a backtrace) reflect an awareness of this problem? In any case, I've attached the gdb-backtrace as well as the one saved via the dialog.
Any more information I can provide?
