Bug description:
[ Impact ]
gnome-shell randomly crashes
[ Test case ]
There's not a real case for this crash, while it's the most recorded in e.u.c
for bionic, there's no a known way to reproduce this.
So, monitoring e.u.c results is the easiest way to check if this fixes the
issue
[ Regression potential ]
Gnome-shell has invalid theme for scrolled views
