Epiphany dying on launch

[Beartooth]

	Running Fedora 18 with xfce4, clicking on "web" often starts
a launch which then dies, without ever getting to a site. 

	The link for "web" leads to the Epiphany site; I have no clue why 
Fedora doesn't call it by its name.

	What could be causing these failures?? And what can I do about it?
