Bug#632985: #632985: gnome-panel do not load

[Luca Bruno]

I think I've encountered the same bug, so here are some details.

> Please explain your problem in more detail.
> Did it happen after an upgrade?

I've stumbled on it after yesterday sid dist-upgrade.
A snippet of dpkg.log for that is attached.

> Do you get any related error messages in ~/.xsession-errors?

(gnome-panel:5802): Gdk-WARNING
**: /build/buildd-gtk+2.0_2.24.5-2-amd64-N7Pg6p/gtk+2.0-2.24.5/gdk/x11/gdkdrawable-x11.c:952
drawable is not a pixmap or window

Upon every start. This also happens when no trasparency or background
images are set. I suspect this is due to some icon, maybe.

> Any other error messages?

When opening the property dialog, I get

(gnome-panel:5802): Gtk-WARNING **: Failed to get constuct only
property adjustment of opacity_scale with value `adjustment1'

and the trasparency slider is unusable.

> Do you have you gnome-panel set to transparent? 

Yes, at least in my case. That seems to be cause that won't let
gnome-panel load.

> Maybe it's duplicate of #633573

It seems so, as the CPU was also completely busy behind gnome-panel and
applets.
 
What's different in this bug, though, is that the panel won't even
appear. So you get a overloaded machine and a non-working DE, ie. the
system is unusable.
It may be worthy raising the severity of this bug, to avoid leaving
other users with a broken desktop.

As a workaround, I had to
change /apps/panel/toplevels/bottom_panel_screen0/background type and
opacity manually, via gconf-editor, in order to get back to an usable
state.

Cheers, Luca
