Just a thought: I see the same warnings, when I "forget" to run grc with
correct priviliges (sudo).

Emne: [Discuss-gnuradio] GRC + N210 + RFX2200 + UHD not working
I'm using grc to generate some extremely simple flowgraphs but I'm seeing very
odd performance. Any idea why I can't seem to get this combination to work? I
have had success with a GRC + USRP2 + WBX + UHD, anybody know why I'm having
issues here?
When I create a flowgraph directly to a null sink (null.png) I receive the
following error:

When I create a flowgraph directly to a fftp sink (fft.png) it just silently
exits with no errors:
