Bug#982255: lutris: segfault after cancelling

[Phil Morrell]

Package: lutris
Version: 0.5.8.3-1
Severity: important


Hi Stephan, lutris reliably crashes when following this sequence:

Sources -> Lutris -> Search "epic games" -> Epic Games Store
-> Install -> Cancel -> Yes -> Install

I've attached the full stacktrace from debugging with:

    $ sudo apt install python3.9-dbg python3-gi-dbg libglib2.0-0-dbgsym libgtk-3-0-dbgsym libffi7-dbgsym
    $ gdb -ex r --args python3 /usr/games/lutris
    ...
    Traceback (most recent call first):
      File "/usr/lib/python3/dist-packages/lutris/gui/widgets/window.py", line 42, in present
	super().present()
      File "/usr/lib/python3/dist-packages/lutris/gui/application.py", line 237, in show_window
	self.app_windows[window_key].present()
      File "/usr/lib/python3/dist-packages/lutris/gui/application.py", line 504, in show_installer_window
	"""Callback to remove the game from the running games"""
      File "/usr/lib/python3/dist-packages/lutris/services/lutris.py", line 150, in install

      File "/usr/lib/python3/dist-packages/lutris/gui/widgets/game_bar.py", line 224, in on_install_clicked

      File "/usr/lib/python3/dist-packages/gi/overrides/Gio.py", line 43, in run
	return Gio.Application.run(self, *args, **kwargs)
      File "/usr/games/lutris", line 567, in <module>
