Please describe the problem:
When running: 

#!/usr/bin/python

import subprocess
import gtk
import vte

w = gtk.Window()
vte = vte.Terminal()
w.add(vte)
w.maximize()
w.show_all()

pid = vte.forkpty(envv=["foo=bar"])
if pid == 0:
   subprocess.call(["env"])
else:
   gtk.main()

I do not have the environment "foo=bar" added.

This might be releated to bug #587894 but even with the patch there
the environment is not added.

Steps to reproduce:
1. Run the above test program
2. Check the output and notice the missing "foo=bar" there



Actual results:
No "foo=bar" in the output

Expected results:
foo=bar in the output of "env"

Does this happen every time?
Yes
