Re: Segmentation fault trying to run gnuradio-companion

Thanks Marcus as always!

I upgraded from Ubuntu 20 to 22 April 2023 and everything has been working since until this week. And it happened after a hard reboot. I don't recall manually installing gnuradio…

Thanks.

Hey, I just saw that your mail where you figured out the command line, and it was too big
for our mail server to forward.

Indeed, the crash log is 3.4 MB of the GTK functions calling themselves in a recursive
ring. Since that's a GTK bug we've never encountered: What operating system exactly are
you on, and how did you install GNU Radio? And: did you perhaps install GTK or pygtk
manually somehow?

Best,
Marcus
