Bug description:
[ Impact ]
GNOME Shell crashes and logs out the user when enabling popular extension
"Window List", which is officially supported by GNOME:
https://extensions.gnome.org/extension/602/window-list/
The root cause of the problem however is not in the extension itself
but in GNOME Shell, which incorrectly tracks stylesheet files that had
already been imported previously.
This was fixed by checking in the stylesheets hash-table whether the
file has already been imported before attempting to import it again.
[ Test Case 1 ]
1. Install the extension
https://extensions.gnome.org/extension/602/window-list/
2. Enable the "Window List" extension
3. Disable the "Window List" extension
4. Enable the "Window List" extension again
5. Verify that GNOME Shell didn't crash
6. Verify that the "Window List" panel is visible at the bottom of the screen
[ Test Case 2]
1. Install the extension
https://extensions.gnome.org/extension/602/window-list/
2. Enable the "Window List" extension
3. Lock the screen
4. Unlock the screen
5. Verify that GNOME Shell didn't crash
6. Verify that the "Window List" panel is visible at the bottom of the screen
[ Where problems could occur ]
GNOME Shell provides the GNOME desktop UI, and thus is a critical
component of Ubuntu Desktop. A bug introduced by this patch would
manifest with missing graphical elements, or the desktop crashing and
logging out the user.
