After installation, euca-run-instances fail unless you run euca-describe-groups first

On karmic running Eucalyptus 1.6~bzr672-0ubuntu3, after installing a node controller and registeringit successfully, it is impossible to run an instance. On the frontend:

On another machine using ec2-api-tools:

etienne@curst:~/AMI/euca-ubuntu-9.04-x86_64$ ec2-run-instances -t c1.medium -k warthogs-key emi-073A1120

etienne@curst:~/AMI/euca-ubuntu-9.04-x86_64$

If I describe the security group, I am then able to launch an instance:

cloudmaster@uec-frontend:~$ euca-describe-groups
GROUP admin default default group
cloudmaster@uec-frontend:~$ euca-run-instances -t c1.medium -k warthogs-key emi-073A1120

Somehow, it appears that the group information do not get initialized properly or something.
