circular import issue.
Yes, moved to the method and its gone :-)
Be careful with doing imports inside functions or methods in library
code - it can cause deadlocks if an application spawns threads as a side
effect of import that then call those operations (see the first bullet
point in
http://docs.python.org/library/threading#importing-in-threaded-code)
Moving components around to eliminate the circular dependency is a
preferable solution (e.g. just looking at the traceback, moving the
definition of KatelloError out of the cli subpackage to an approporiate
location in the core subpackage and providing an alias in the old
location may be a more robust long term solution than just delaying the
import).

Nick.
