Crash in track fitting because of plotting

[coquelin77]

Plotting should never cause a crash. Traceback:

@coquelin77 Does the GUI actually crash or is the exception caught in the exceptions window? Usually any exception raised during plotting should be caught and handed through to the exception window.

I'm closing this since the GUI doesn't crash but behaves as expected and opens an exception window.

It was not a GUI related bug, since the GUI behaved as expected, I agree. But it is a plotting bug that I implemented 2 years ago ;-).

Ah, okay, so I'm reopening this then but removing the gui label.
