Problem with latest version (master) of gr-osmosdr

Thank you, Fabian!

I followed your advice and was able to successfully build the full 
Gnuradio system.

Using an dongle, I am able to run osmocom_fft with expected 
results.  However, on exiting osmocom_fft (or other oscmocom programs) I 
get a lengthy set of error messages.  I also saw this with my earlier 
attempts to work around the build problem.  I wonder if there is another 

Here is a screenshot showing the beginning of the console output.  Do 
you know what might be causing this?
