appindicator doesn't honor the color key in -symbolic icons

[Sergio Costas]

I'm creating an app that uses libappindicator to add an status icon to the bar. I want to ensure that the icon remain visible no matter what background color is being used in the upper bar, so I followed the "-symbolic" standard from freedesktop. It specifies that icons whose name ends with "-symbolic" will have fills with #BEBEBE color replaced by the current FG-COLOR, allowing them to be visible both with dark and light backgrounds.

I did it and it worked fine under Gnome-Shell, but not with unity (I tested both my current 12.04 system and a 12.10 in a virtual machine). I made several tests, both with my own icons and other system icons which are "-symbolic", but no results.

Several notes about symbolic icons:

Thanks.
