I didn't manage to fully reproduce the bug, but from what I've seen in Scott's backlog, the key (which is the monitor name) was empty. That means that for some reason his monitor was not detected correctly at a previous stage. I've fixed the display code to take into account the race condition where the monitor name is NULL, so now you should see a warning instead of a segfault. Could you please take some time to verify that the branch above works for you and you don't get the segmentation fault anymore? Thank you!
