Trying to unlock VeraCrypt volume with wrong password can crash GNOME Shell

This has been reported by so many Whisperback reports that I'm reporting it even if I can't reproduce it.

Here are some reports:

  • "Sorry, that didn't work. Please try again." as expected, then the GNOME session crashes, and after some time we're back to GDM without the Welcome Screen app
