Qviewkit automatically closes for 2D time domain data

[TimWolz]

I can't display my 2d time domain data with qviewkit. When I click on amplitude or phase in the gui. The plot window shortly opens but then the complete qui closes...

Please provide a traceback from command line or a sample file.

There you go P83GHM_time.zip

and Traceback:

I had the same issue (the one I mentioned in the dev meeting)

As far as I remember it occurred both on Linux and Windows

I can confirm the issue on my office computer in the master branch. The file opens in the qvk_2 branch where we work on qviewkit but I don't know (yet?) why this is no issue there. I've had some troubles with pyqtgraph's ROI in the past, IDK if we need this in qviewkit at all.
