[Bug 49341] "Programming error" when moving transparency slider of gnome-panel background from transparent to opaque.

[Lars Schöning]

Public bug reported:

Binary package hint: gnome-panel

When moving transparency slider of gnome-panel background from
transparent to opaque a set of "programming errors" comes up on my
machine.

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

I was not able to copy all of them because the system panel is
unresponsive during that time and I was only able to store one message
in the clipboard.

The error only comes up when the slider reaches "Opaque".
