Pymol crash

[Robert Welch]

Pymol version 1.8.2.1

Python version 2.7.12

OS: Ubuntu 16.04 LTS

Very odd error. Runs perfectly (loading, viewing playing back etc) until after the last frame is loaded, then crashes with this error.

Will take a look at what happens in the plugin after the trajectory is loaded.

[Robert Welch]

If mtTkinter is present, the viewer will now import that instead, which is a thread-safe version of Tkinter.

Given that the crash only happens when the trajectory has been fully loaded, it seems likely that there is another way to fix it. But the release candidate is due tomorrow!
