Thanks for your report. This has been reported upstream at http://forum.amule.org/index.php?topic=14654.0

Is this easily reproducible? If so, what are the steps to reproduce it?

[Francesco Palermo (francesco-palermo)]

I received the same backtrace today. Amule crashes in a few minutes.
I can't say how to reproduce this bug, but I obtain this strange behaviour after some new downloads have been added.

[gabriel (gabriel-castro)]

I also have this problem, but I can't reproduce. Seems to occur randomly.

[David McNeill (davemc)]

I can confirm the above crash. Exactly the same backtrace.

Linux mctui 2.6.24-18-generic #1 SMP Wed May 28 19:28:38 UTC 2008 x86_64 GNU/Linux

Running Kubuntu

This post http://forum.amule.org/index.php?topic=15259.0 on aMule doesn't leave much hope that upstream will fix it.

There's also lots of duplicates of this bug reported on aMule forum, since that's what they ask for in the backtrace output...."Please assist us in fixing this problem by posting the backtrace below". Give only 1 in 10 or 1 in 100 people report it, there's got to be a lot of instances out there.

It's a pest, because when aMule crashes, you can loose your place in remote queues, meaning you have to wait ages, suffering 4:1 uploads until you get some download slots again. Costing me Gb's of data a day. Especially when aMule crashes a few minutes after bedtime, wasting a whole nights access.

I guess the only workaround is to get a newer version from svn.

Has anyone done a substantive analysis of the backtrace?

[David McNeill (davemc)]

It seems that this bug is probably covered by a fix coming in this report....

[Oibaf (oibaf)]

This should be fixed in amule 2.2.2-1ubuntu1 (Ubuntu 8.10). For Ubuntu 8.04 see bug #244670.
