[op25-dev] op25 scope.py issue

[lists@lazygranch.com [op25-dev]]

I built gnuradio from source. It passes the "make test". 

uname -a
Linux linux.suse 4.4.49-16-default #1 SMP Sun Feb 19 17:40:35 UTC 2017 (70e9954) x86_64 x86_64 x86_64 GNU/Linux

I'm using the KDE Plasma desktop. I can set the gtk2 theme to whatever the developers prefer.
