This sounds like a dependency problem in packaging rather than a problem in horizon. Please work with the Debian packaging team on this (https://wiki.openstack.org/wiki/Packaging/Debian). If this is identified to be a bug with horizon proper, then feel free to re-open the ticket and add details on how it can be reproduced. Thanks.
