I have the same problems with my Lufthansa *G card. As German resident you get a free credit card that is as well your FF-Card. It is a normal Master Card with additional *G and FF-Number printed on the card.
No problems in LH-Land.
With third party lounges I have problems on rare occasions:
"Sir this is not a frequent flyer card - this is a credit card"
Payed lounges just wipe your card and you pay the entrance fee.
I am not 100% sure about fraud if I hand over my credit card to a weird person in a weird country. So for those cases I got a 2nd card from LH - they did understand the reasons. I am perfectly happy with most of my travels but if I travel on other *A airlines or dodgy countries I just take my plan FF-Card.
