Summary

0001726: Amuled and amulegui use 100% CPU when removing someone from the friends list

Description

Hello,
I'm forwarding the debian bug https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=693617: [^]

>>>
I am using amuled and amulegui, and whenever I remove someone from the friends
list (in the messages screen) amulegui and amuled start consuming lots of CPU.
I need to kill amulegui in order to restore normal CPU usage, and even after
that amuled takes some time to normalize.
<<<

>>>
I've run amulegui through gdb, and this is what I got:

Program received signal SIGINT, Interrupt.

After that, I did the same with amuled, but there were many different
threads:

Thread number one was the more suspicious, as it was stuck in the same
function as amulegui, so I did the backtrace of this one:
