location of an Epiphany extension...

[Marimpis Avraam <makism venus cs teicrete gr>]

Hello, i was wondering if and how is possible to determine whether
an extension is loaded from "/usr/lib/epiphany/extensions/" or 
"~/.gnome2/epiphany/extensions/".

I`m asking this, because i`m writing a python extension that depends
on a Glade file. I could just use some "try-except" block, to check the 
existence of that Glade file, but maybe there`s an "official way"-or 
something?


Thanks in advance
Makis
