admob problem?

Some time in the last week or two (hard to tell exactly, w/o version control on plugins) started seeing these in the logcat from admob, and when it appears then you have trouble requesting/receiving ads:

W/ActivityManager(  577): Permission Denial: opening provider com.google.android .gsf.gservices.GservicesProvider from ProcessRecord{28c8f4b8 5221:mydomain.myappname /u0a218} (pid=5221, uid=10218) requires com.google.android.pro viders.gsf.permission.READ\_GSERVICES or com.google.android.providers.gsf.permiss ion.WRITE\_GSERVICES

Is it an admob problem? (as of built today)

Or an GPlay Services problem? (have 6.7.6)

Or an Android problem? (have 5.0.2)

thx for any tips
