getExistingDirectory Broken (cant select, corrupted path, no default path)

Reopening as suggested PYSIDE-1150

So, briefly: I cannot select directory by

QFileDialog.getExistingDirectory

on ubuntu 20.04 GNOME.

Iinstead of selecting the directory, it just enters to the directory

the workaround is to set options

QFileDialog.DontUseNativeDialog

But this is just a workaround and it looks ugly
