epiphany doesn't start

[Enrico Teotti <enrico teotti virgilio it>]

Hi,
I have debian sid with epiphany installed. It was working until  
yestarday. Today it doesn't, I click on the gnome menu's to launch  
epiphany but nothing happens. If I try lo load it from console the  
system waits and nothing happens.
What can it be? Can I find an epiphany log file?
Thanks,
Enrico
