Comment 10 for bug 1364780

In answer to @martyn-lanedo: I'm not sure how to reproduce this reliably, except that it happens for me in *every* ubuntu-gnome session (15.04) within 15 minutes or so of login. But it seems to be triggered by a background tracker action, not by an attempt to extract a particular file directly. If you can suggest a way of identifying which file was being extracted at the time of the crash, I can try to identify it.
