Bug#550933: [gnome-panel] Panel jumps from bottom to top when switching between internal and external monitor

[Jakob Lell]

Package: gnome-panel
Version: 2.28.0-1
Severity: normal

--- Please enter the report below this line. ---

I am using a notebook which is sometimes attached to an external 
monitor. When I switch from the external monitor to the internal 
notebook display or vice versa, the panel on the bottom of the screen 
jumps to the top automatically. I have to manually go to the preferences 
of the panel and set the orientation from top to bottom again. This 
occurs regardless of whether I use xrandr manually or use the gnome 
display preferences applet.

There is a similar bug report in the ubuntu bug tracker since April 2009:

https://bugs.launchpad.net/ubuntu/+source/gnome-panel/+bug/355848

However, this bug has been marked invalid in May 2009. I am using debian 
unstable and this behavior has changed quiet recently (not more than a 
few weeks ago). I don't know whether this bug has the same cause as the 
ubuntu bug.
