Sound Indicator not obeying Theme Configuration

[Scott Moore]

After upgrading to 14.04, the sound indicator is not changing it's 
background color to match the color chosen in the Theme Configuration 
for custom panel colors. I reported this problem about a week ago and 
Pasi said it's likely because I'm using an older version of gtk. I went 
ahead and did a fresh install and the problem is still there. Do I file 
a bug against the indicator or theme configuration? A pic of the issue 
can be seen here. http://www.scottbomb.com/image/temp/trusty_indicator.jpg
