Hello,
At one point I had gnuradio companion working just fine. But while trying to get the software to recognize my blade-RF device, I somehow came to a point where I was getting the Segmentation fault error when trying to open companion. I uninstalled and reinstalled gnuradio, but I am still getting the same errors. I stack traced companion and found where the core dump happens. I took the last 15 lines of the trace and pasted them below.
