epiphany-browser segmentation fault with proxy.pac

Please replace the title by "epiphany-browser segmentation fault with any url"

Indeed, the browser crashes for any address.
Methodology:
$ Epiphany-browser
-> Enter an address in the address bar
= The browser crashes

I tried with "epiphany-browser www.google.com", epiphany-browser """, "epiphany-browser "*"" but all these commands works fine for me with same epiphany release, please could you install epiphany-browser-dbg package and give another examples that are crashing your browser? sorry for asking but I can't reproduce it.

I tested with the url ubuntu.com

But, it works without problems if i disable global proxy configuration
in ubuntu :
->System
-->Preferences
--->Proxy
---->Tick "direct connection to internet"
----> Apply to the system

Please rename this bug : "epiphany-browser segmentation fault with proxy.pac"

[Expired for epiphany-browser (Ubuntu) because there has been no activity for 60 days.]

I have here the problem since migration from lucid to natty.
If i switch the gnome-network-preferences from "direct connection" to "automatic proxy configuration" epiphany crashes.
With "direct connection" no problem occurs.
