Description Soeren Apel 2020-08-29 16:33:58 CEST
main() creates an instance of Application which is a QGUIApplication. Without a valid X server, this will segfault.

How to reproduce:

export DISPLAY=
pulseview --version

How this can potentially be fixed:

pulseview --version -platform offscreen
pulseview --version -platform minimal

However, it's unclear at this point how exactly the -platform paramter prevents the xcb/windows/etc. platform plugins from being loaded and loading offscreen or minimal instead. There's no documented API to perform this, see https://doc.qt.io/qt-5/qpa.html
