I'm a bit skeptical due to the small sample size, but let's consider this fixed until proven otherwise. 1169806 2 mcatanzaro 2016-03-02 03:53:17 -0800 Just kidding, our crash server got confused and split the reports. I have 338 reports of this in February alone, under a slightly different backtrace. 1214171 3 mcatanzaro 2016-07-25 07:43:06 -0700 1327 reports of this in Fedora so far, first occurrence is last November. (Spread over so long, it's not as many as it seems.) I think it's probably a regression from our recent GNOME shell browser plugin changes. 1245567 4 cgarcia 2016-10-28 06:20:43 -0700 This is a bug in the plugin, see the meta bug.
