[BUG] Random crash on startup - possible race condition #44
Description
I noticed that sometimes when I open this tool from the applications menu, it wouldn't open, yet other times it does.
I decided to test it on the command line, and here are the results of opening the application 6 times:

As you can see, out of 6 times, it only opened properly 3 times, and the occurrence of the crash doesn't seem to be consistent, nor do we get any extra messages printed before it occurs.
