Installing the new Iceweasel 3.5.6 breaks Epiphany

[Javier <javuchi@gmail.com>]

As the title says, installing the new Iceweasel 3.5.6 breaks Epiphany 
(not the package, but the application itself). If you try to starts 
Epiphany after the update, you obtain a "beatiful" segment fault.
I suppose that this is because Epiphany is incompatible with the new 
Gecko engine.
