Description of problem:
gnome-terminal background transparency is reset to zero after the last window is closed (which means all terminals are completely transparent at login)


Version-Release number of selected component (if applicable):
gnome-terminal-3.6.1-1.fc18.x86_64

How reproducible: always


Steps to Reproduce:
1. choose a profile, set its background to transparent and set transparency to a value between 0 and 100%
2. all other terminals with the same profile are affected immediately
3. close all terminals with the same profile
4. open another terminal with the same profile as before
  
Actual results:
new terminal is completely transparent (opacity is reset to zero)

Expected results:
transparency settings should be persistent

Additional info:
This has already been filed on Jun 2012 as bug 832716 but it might go unnoticed for F18 since it was filed for F17, thought I should open a new issue for F18.
I filed this bug upstream as well [https://bugzilla.gnome.org/show_bug.cgi?id=692753] and the response was: "Looks like a gconf bug to me; there's no code writing to the opacity gconf key when creating a new terminal."
