Hello,

It's been a while since I was able to use gnuradio due to getting a son,
but I've finally found some time to reinstall everything using Pybombs.

I got almost everything to work, even fosphor. The only thing that gives me
issues is osmocom_fft.
Here is the traceback:


Traceback (most recent call last):

wx._core.PyAssertionError: C++ assertion "m_window" failed at
../src/gtk/dcclient.cpp(2043) in DoGetSize(): GetSize() doesn't work
without window


My system is running kubuntu 17.04, that is a kde distribution. So I
suspect that some gui library package is not installed. Does anyone have a
idea on what is going wrong here?

Thanks in advance,
Hans Van Ingelgom.
