Numeric.concatenate

I have searched the archives for this problem (if it truly is one) and
could
not find it so I am seeing what anyone knows.

when I go to run ./usrp_wfm_rcv.py I get this error which keeps
repeating
itself as I listen to the radio station.

Traceback (most recent call last):
File
“/usr/local/lib64/python2.5/site-packages/gnuradio/wxgui/fftsink.py”,
line 276, in set_data
points[:,1] = Numeric.concatenate ((dB[L/2:], dB[0:L/2]))
ValueError: matrices are not aligned for copy

Thanks,

Newell
