Terminated after throwing an instance of 'std::bad_alloc'

I've noticed that for weeks now that whenever I use amule it seems to spontaneously quite after being left to run for several hours. So I invoked it from the command line to see if any error message would be written when it spontaneously quit. And there was. The output was:
