Selecting export file during lock causes GUI crash

[andrewvh4]

Using Linien 0.7.0 on Linux (Ubuntu) installed via pip:

Before locking the system, when I click Select File button under 'Exportin theView` tab, the system file dialog opens as expected. I am able to set a file name and export the data.

After locking the system, when I click the Select File button, the application freezes and greys out. If I had selected a file beforehand, I am still able to Export the data to the selected file.

This issue was not observed on Windows versions 0.7.0 and 0.6.0.

Thank you for your bug report and sorry for the late reply, this somehow slipped through.

I could imagine this has something to do with

linien/linien-gui/linien_gui/ui/main_window.py

Line 101 in a1c3c38

# options |= QtWidgets.QFileDialog.DontUseNativeDialog

I did have some issues with (non-)native dialogs and PyQt in the past related to this option. Unfortunately, I do not really use any Linux Desktops at the moment so hard to test for me. But maybe you could play around with this?
