image store broken on Lucid

The basic operation of installing an image from the image-store-proxy in Lucid is broken.

Once the image downloads, an error is report (see screenshot).

The error message is:

Command 'euca-bundle-image' returned status code 1:
'NoneType' object has no attribute 'endswith'

Bundles an image for use with Eucalyptus or Amazon EC2.

euca-bundle-image -i, --image image_path -u, --user user [-c, --cert cert_path]
[-k, --privatekey private_key_path] [-p, --prefix prefix] [--kernel kernel_id]
[--ramdisk ramdisk_id] [-B, --block-device-mapping mapping]
[-d, --destination destination_path] [--ec2cert ec2cert_path]
[-r, --arch target_architecture] [--batch] [-h, --help] [--version] [--debug]

REQUIRED PARAMETERS

-i, --image Path to the image file to bundle.

-u, --user User ID (12-digit) of the user who is bundling the image.

OPTIONAL PARAMETERS

-c, --cert Path to the user's PEM encoded certificate.

-k, --privatekey Path to the user's PEM encoded private key.

-p, --prefix The prefix for the bundle image files. (default: image name).

--kernel The kernel to be associated with the bundled image.

--ramdisk The ramdisk to be associated with the bundled image.

-B, --block-device-mapping Default block device mapping for the image (comma-separated list of key=value pairs).

-d, --destination Directory to store the bundled image in (default: "/tmp"). Recommended.

--ec2cert_path The path to the Cloud's X509 public key certificate.

-r, --arch Target architecture for the image ('x86_64' or 'i386' default: 'x86_64').

--batch Run in batch mode (compatibility only. has no effect).

-a, --access-key User's Access Key ID.

-s, --secret-key User's Secret Key.

-U, --url URL of the Cloud to connect to.

--config Read credentials and cloud settings from the
    specified config file (defaults to $HOME/.eucarc or /etc/euca2ools/eucarc).

-h, --help Display this help message.

--version Display the version of this tool.

--debug Turn on debugging.

Euca2ools will use the environment variables EC2_URL, EC2_ACCESS_KEY, EC2_SECRET_KEY, EC2_CERT, EC2_PRIVATE_KEY, S3_URL, EUCALYPTUS_CERT by default.

Mathias says that the $HOME environment variable is not set in the python twisted environment were euca-bundle-image runs.
