[Bug 78670] Problem when changing opacity of taskbar

[oceylantr]

Public bug reported:

Using Ubuntu Dapper Drake 6.06 LTS with all available official and wine
updates...

There was no problem like that before. When tried to change opacity of
taskbar to full color (no opaque) from properties menu, a message like
that is shown :

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

That is said to be a small problem so it is. It doesn't make any trouble
but it is necessary to mention about
