** Description changed:
[ Impact ]
If an app doesn't implement startup notifications correctly (but
declares them supported in the .desktop file) then gnome-shell might
think the app is still starting for 15-20 seconds after it launches. If
a garbage collection run happens in this time, or you simply log out,
then gnome-shell will crash in shell_app_dispose()

[ Test Plan ]
- WIP
+ 1. Install an affected app like Chromium or Google Chrome.
+ 2. Launch the app and then immediately close the app and log out of GNOME.
+ 3. Verify there are no new files in /var/crash from gnome-shell or that the
system journal does not mention "ERROR:../src/shell-app.c:shell_app_dispose:
assertion failed: (app->state == SHELL_APP_STATE_STOPPED)" from during the
previous session.
[ Where problems could occur ]
Only shell_app_dispose is being modified so the only places that could
experience a change in behaviour are:
- * during logout; or
- * during a garbage collection pass, which can happen at random times.
+ * during logout; or
+ * during a garbage collection pass, which can happen at random times.
The worst (maybe only) scenario would be for the fix to introduce
another crash in the same location, at the same time as the old crash.
