[Digikam-users] Digikam Crash when changing metadata (rotating, assigning flags or keywords)

The fix is simply to add a couple of overlooked lines to makernote.cpp

            { "-",              casioId,     0,              newIfdMn2       },
            { "-",              casio2Id,    0,              newCasio2Mn2    }
