Comment 0 for bug 826037

I've installed Nova trunk and Nova milestone and configure it (Trunk is nova_2011.3~d4~20110812.1423-0ubuntu0ppa1~natty1).

Everything looks operational until I run:

$ euca-describe-images

And get:

UnknownError: An unknown error has occurred. Please try your request again.

The /var/log/nova/nova-api.log returns:
