5.5.1, 5.7.1

OS X 10.11.3
I'm not entirely sure which version it affects, but presumably the latest major version. I'm using a snapshot of mumble from http://wiki.mumble.info/wiki/Main_Page. The binary appears statically linked so I cannot tell which version exactly.
I'm able to inconsistently trigger it by turning my displays off in OS X. It is not sleeping, the displays are simply being turned off either by using the hot corners feature or physically turning them off. If it is not straightforward to figure out I can install the Qt development environment and compile Mumble myself to try to track it down further. My assumption is that it just needs a simple null check or two but I am not particularly familiar with the Qt code so I could be mistaken.
