Crash when opening a new dialog

[Offpics]

Whenever I try to open a new dialog like, e.g. "Open Cheat Table", PINCE crashes and prints this output to the console:

/PINCE.py:1066: Warning: g_object_get_is_valid_property: object class 'GtkSettings' has no property named 'gtk-fallback-icon-theme'
  file_paths = QFileDialog.getOpenFileNames(self, "Open PCT file(s)", pct_file_path,

OS: EndeavourOS/Arch
DE: Gnome
Windowing System: Wayland with xorg-wayland

For anyone wondering, I've been able to fix it by installing qt5ct and launching it. Maybe worth mentioning this in the README.md?

Maybe worth mentioning this in the README.md

Yeah, definitely

Closing this issue since a fix was found

NB: When running qt5ct I got an error that I needed to change my environment variable QT_QPA_PLATFORMTHEME from gtk2 to qt5ct. Making that change resolved the issue for me.

This crash seems to be specific to gnome, thank you for sharing your wisdom @jaredballou. Your solution works just fine
