Bug description:
[ Description ]
GNOME shell crashes on restart when some window actors are opened
[ Test case ]
- Run gnome-shell in Xorg, start some windows
- Hit Alt+F2
- Write 'r' and press Enter
- The shell should restart without crashing in
meta_workspace_list_windows
[ Regression potential ]
Javascript errors might be emitted when trying to access to
invalidated data, but nothing really harmful.
[ Note ]
This crash doesn't affect versions after 3.28 for various reasons:
- The JS code triggering it isn't there anymore
- MetaScreen doesn't exist anymore.
Similar crashes might happen in newer versions, but as per different
code paths, and so to be reported as different bugs.
