Problem: When I run gnuradio-companion and then just select the window and move the mouse around or try to resize the window, the program generates a segmentation fault. I don't even have the opportunity to load any models and usually only have to wait <10 seconds before the crash.
OS: Ubuntu 18.04
I did read about other seg faults with GRC, but none quite matched my situation. One suggested running gdb to get a backtrace, which I did and why I believe the problem is GTK related. The backtrace is given below from PyBOMBS installation.
My initial gnuradio installation was via apt-get. Thinking that was the problem, I removed it and used PyBOMBS following the instructions at
https://www.gnuradio.org/blog/2016-06-19-pybombs-the-what-the-how-and-the-why/, which matches others I've found. When that still didn't solve the problem, I tried compiling from source, although I tested it before running 'make install'. No luck there either, and I couldn't figure out how to get some of the dependencies so I'd prefer to use the Pybombs version.
I'm not ruling out a conflict somewhere, but the backtrace seems to indicate a GTK problem. Any ideas? Need more info?
Thanks!
