Longer backtrace downstream. 1252659 1 mcatanzaro 2016-11-18 05:44:23 -0800 Two user reports: "Go to GNOME Activites, type "problem reporter" (crashes about two symbols before the end)" "I ran into this crash when closing yelp after searching for something in a help document." The actual crash count is useless (it's >22,000 but it's obviously wrong). 1254746 2 cgarcia 2016-11-30 05:47:09 -0800 This is 2.13.90, I think this crash was fixed later in 2.14 branch by merging r205852. Feel free to reopen if you see this crash again with 2.14 or trunk.
