Public bug reported:

Without warning (i.e. epiphany had been working perfectly well for

The only change I've recently made to my configuration is I'm
temporarily on a different network that requires use of this proxy
configuration: http://www.it.usyd.edu.au/proxy.pac, rather than the
direct connection I usually have.

** Affects: epiphany-browser (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed
