Not sure if this is the same trigger, but I was seeing similar messages today. In this case, the cause was that a local build of mono had recently been installed on Ubuntu 12.04 but ldconfig had not been run. This meant that the simulators failed to load /usr/local/lib/libMonoPosixHelper.so which stopped simulators properly compressing avatar data for transfer, resulting in errors like this.

However, it's probably the case that a bad incoming stream data in general would trigger this exception.
