EASA issued SAFA ramp Inspection Guidance Material (GM) in July 2009. The only references to "Log Book" is under item A21 which concerns the Journey Log (ref EU OPS 1.1055), and a refrence in the Definitions section regarding the Tech Log.
Flight Crew Licences are covered under item A20 of the GM. There is no material requiring SAFA inspectors to sight your personnal flying log books. I would suggest that certain individuals are taking it upon themselves to do this (and possibly over stepping their remit).
PS JAR OPS 1 suceeded by EU OPS effective last year.
Hope of help.
