minor issue : gnome, epiphany and iceweasel

[Matej Kosik <kosik@fiit.stuba.sk>]

Hello,

When listing text-files in gnome-terminal, if those files contains URLs, gnome-terminal enables me to follow those links by starting a web-browser.
This is handy.
However, I have noticed some confusing behavior.

When I follow HTTP links, e.g.:
http://www.youtube.com/watch?v=Yg0tVUnLOAM
iceweasel is started. This is fine and exactly what I want.

When I follow FILE links, e.g.:
file:///usr/share/doc/libbitstring-ocaml-dev/html/api/Bitstring.html
epiphany is started. I do not understand why epiphany and not iceweasel.

Releavant "alternatives" are set up in the following way:

  kosik@debian:~$ l /etc/alternatives/|grep www
  lrwxrwxrwx   1 root root    18 May  8 11:08 gnome-www-browser -> /usr/bin/iceweasel
  lrwxrwxrwx   1 root root    34 May  8 11:08 gnome-www-browser.1.gz -> /usr/share/man/man1/iceweasel.1.gz
  lrwxrwxrwx   1 root root    14 May 11 11:32 www-browser -> /usr/bin/links
  lrwxrwxrwx   1 root root    30 May 11 11:32 www-browser.1.gz -> /usr/share/man/man1/links.1.gz
  lrwxrwxrwx   1 root root    18 May  8 11:08 x-www-browser -> /usr/bin/iceweasel
  lrwxrwxrwx   1 root root    34 May  8 11:08 x-www-browser.1.gz -> /usr/share/man/man1/iceweasel.1.gz

"System / Preferences / Preferred Applications" also refers to iceweasel instead of epiphany.

So I do not understand why epiphany is started. Can somebody give me a hint? Is this somehow hard-coded in gnome-terminal or can it also be configured.

Thank you in advance.
