epiphany crashed with SIGSEGV in __kernel_vsyscall()

Binary package hint: epiphany-browser

Was mucking around with the font settings trying different combinations of hinting and sub-pixel antialising when the epiphany browser I had open in the background crashed. It appeared to coincide with a change in settings but may have just been a fluke. I had a few windows open but wasn't on any particularly whizzy site, unless I had arstechnica.com open on a page with Flash adverts.
