[ Impact ]
gnome-shell crashes
[ Test case ]
1. No clear test case for this issue.
Some extensions (clipboard indicator) seems to trigger it, but there's
no an an easy and reproducible test-case for this so far.
So install "clipboard indicator" indicator and expect this to run
properly.
[ Regression Potential ]
Nothing really should be regressing.
Labels could not be updated correctly on disposed labels (not destroyed yet).
