Viewing words does not work on Ubuntu 18.04

[Logan84]

When following the steps, there have been two times that the simulation crashed. When hitting the [Wt Words] button, the simulation crashes. When hitting the TrainEnv and then on Words to see a list of all the words, the simulation crashes.

could you run from a terminal and post the stack traces of the crashes?

btw I just got a crash in Wt Words by keeping the window open and hitting the button again -- I will fix this one -- is it the same that you got?

I can't replicate the 2nd crash though, on mac

[rcoreilly]

first one is fixed.
