Just experienced this on Ubuntu 11.04 alpha3 when using uec-run-instances from the cloud-utils package. To reproduce:

sudo apt-get install cloud-utils
--- setup Amazon EC2_PRIVATE_KEY and EC2_CERT environment variables
uec-run-instances -l your-launchpad-id -t m1.small --wait-for=ssh ami-da3eccb3

Result:
