Affects: ubuntu-artwork (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
When using the Human theme, GtkDialog nesting a GtkComboBox (for example
gnome-sound-properties or gimp layer tool) have a white background when
all other windows have a grey background.

This problem is visible in the attached screenshot. I don't think it is
a problem in the application as the attached very simple program
exhibits it.

For information :
$ dpkg --status ubuntu-artwork
Package: ubuntu-artwork
Version: 6
