246 reports of this one in Fedora, first report is last December. Yet another likely regression from GNOME Shell browser plugin changes. ("Regression" in the sense that after fixing the old crash, now these new crashes appear.)

This is a duplicate of #137425, it's calling invokeDefault with an invalid npobject in both cases. *** This bug has been marked as a duplicate of bug 137425 ***
