If there is a datastore within a datastore (e.g. BB_ORIGENV) then
get-hash() doesn;t correclty handle the contents using the memory
address instead of the contents.
This is a patch from dominik.jaeger@nokia.com which addresses
this problem. Its been low priority since we don't include
BB_ORIGENV anywhere this would cause an issue as standard.
