The aeolus-image command-line tool was providing a facility to 'list' various image information. When listing images in a specific environment, the command was failing if the provided environment name contained whitespace. A sample command that results in failure would be:
# aeolus-image list --images --environment="Devel Cloud"
This issue will be resolved in a future release of Red Hat CloudForms. Until this issue is resolved, administrators may prevent the problem by removing all whitespace from Cloud names.
