Unable to see baseband signal.

From readme:

Thanks for the bug report. One clarifying question: did the error occur immediately after hitting enter on the command line? Or did you click anything in the GUI first?

[bdn76]

First one.

I'm experiencing exactly the same issue, any workarounds yet?
I'm able to start the GUI, however, the graph stays blank after opening the provided test files.

I tried to reproduce this error with the following steps:

• installing Ubuntu 16.01 LTS on a fresh partition
• installing all system updates
• installing gnuradio via pybombs (instructions at http://www.fieldxp.com/Chapter-2-Installing-the-Software.pdf)
• installing other pre-reqs listed in README
• running the following:
  ./waveconverter.py -q ../input_files/fan_all_dip1101_pruned_dec_c304p55M_s830k.iq -o ../output_files/test.log -g -p 3

I did see the "list index out of range" error, which must have slipped past my last regression. This error, however, did not impact anything, and I was able to hit the demod button and see the baseband waveform.

mnaujokas - does anything happen when you hit the demod button?
bdn76 - can you tell me anything about your setup? for example, how did you install gnuradio?

Thanks for your patience all.
