Open Stack

Hey all,

since quite some weeks I am getting an error page instead of the "Instances
and Volumes" page in the
Essex Horizon Dashboard with the above title and the below detailed error
output:

now I wonder in how far that is a bug in the software and/or whether I have
an invalid entry in my nova database that
I can fix by hand.

if so, does anyone know how to actually work around this? I do really need
this (now not working) page :-)

Christian Parpart.
