[Discuss-gnuradio] Confusing Error

[dromza]

I wanted to make a post to see if someone could help me out with a problem I am
 having with GNURadio.

 The version of linux I am running is Ubunto (Intel x86 Edition). I am using a
 laptop (Dell Latitude with a Pentium III).

 I installed GNU radio from the tarballs given on the GNU Radio Project website.

 I was trying to run wfm_rcv_gui.py from gnuradio-examples-0.4.

 I ran this command: sudo python wfm_rcv_gui.py 95.3

 and this is the error message I was given:

 RX d'board A: Invalid EEPROM contents
 RX d'board B: <none>
 usrp_standard_rx::set_decim_rate: WARNING rates > 128 result in incorrect gain.
 >>> gr_fir_fff: using SSE

 AttributeError: 'PySwigObject' object has no attribute 'max_streams'

 I do not know how to fix this and any input would be appreciated.

 Thanks,
