ntdrivers.tdb is ok, it appears to be ntprinters.tdb which is processed
afterwards. My guess is it's a reoccurrence of:
Windows (likely the fault of the printer driver) sometimes adds
garbage after the null terminator for printer device mode strings.
Unmarshalling of the device mode chokes in some cases when processing
The changes for 8606 fixed spoolss_DeviceMode (spoolss.idl)
unmarshalling. However, it looks like we also need to do the same for
ntprinting_devicemode (ntprinting.idl) to handle cases where this
garbage was stored in the tdb, prior to the 8606 fix.
Again, please raise a bug so we can fix this. Attach your printing tdb
files in addition to the logs please.
