It's because there is a module glance.store.swift and a module swift.common.client. Local namespacing is confusing Python into thinking it should search for "common.client" at a module path of glance.store.swift.common.client. It's a bug, and there are a couple solutions to it. Rick refers to a couple below. Working on it...

Thanks!
