Apparently this is caused by a rogue Gnome Shell extension. Running
gnome-shell inside a gdb session reveals the following BT after the
crash:

The clue is in the invocations inside of libjs which eventually lead to
the g_assertion invocation failing and the subsequent SIGBABRT. After a
little bit of try and error, it turns out that disabling the extension
Topicons Plus causes the issue to disappear.
