Open Stack

Dear All,

I have given a try to Thermal (Heat Horizon extension) on Ubuntu 12.04 
with a simple Wordpress template.
OpenStack version is Folsom 2012.2.2-dev 
(2012.2.2-LOCALBRANCH:LOCALREVISION)
Heat version is few days old install from trunk. There is no version 
output with the heat CL.
With that simple template, stack create and delete appeared to work 
correctly. However, the "Catalogues" view blows out completely with an 
Internal Server Error: "An unexpected error occurred while processing 
your request. Please try your request again.". Apache gets the request.

129.183.148.30 - - [05/Apr/2013:07:59:44 +0000] "GET 
/horizon/i18n/js/horizon/ HTTP/1.1" 200 2425 
"http://10.197.217.60/horizon/thermal/catalogues/" "Mozilla/5.0 
(Macintosh; Intel Mac OS X 10.6; rv:19.0) Gecko/20100101 Firefox/19.0"

However, there is no error logs at all to help out with troubleshooting 
the problem. Any idea what could be wrong?
Thanks
Patrick
