[Bug 57384] Panel opacity.

[neko]

Public bug reported:

I get this error when setting the Gnome Panel to opaque:
Traceback (most recent call last):
  File "/usr/lib/python2.4/site-packages/deskbar/ui/cuemiac/Cuemiac.py", line 667, in on_change_background
    style.bg_pixmap[gtk.STATE_NORMAL] = pixmap
TypeError: can only assign a GdkPixmap or None

Reproduction:
Right click panel.
Select Properties.
Go to Background tab.
Select the Solid Color radio button.
Drag the Style slider all the way to Opaque
An error should come up.
