Encoding PosKey

Hi,
i have som problems PosKey Error that seems to be related to some kind of Encoding problem.

if i try to check the catalag with zencatalogscan:

Traceback (most recent call last):

if i try to run a reindex() from zendmd i get this:

raise POSKeyError(oid)
POSKeyError: 0x10495474

guess it would be a good idea to find the device that creates this problem, any one knows how to solve this
