Segmentation fault

[leaf-node]

I was streaming a video and clicking around in the interface, on the streaming stats button, and other parts of the interface, trying to reproduce #44. I then switched to another window. When I went to switch back, I noticed that HUBAngl had crashed. My system is apparently not configured to make core dumps. I suspect that Python segfaults may be due to errors in C-based library wrappers, or due to a lack of library input sanitation / testing.

I reproduced this issue one more time by clicking around in the interface, then minimizing the HUBAngl window. After that, I tried again, but wasn't able to crash it.
