Did you set your location properly on your profile screen? This is important to get the correct location.
I suppose it could be some claim error that happens in conjunction with the segfault.
But it could also be rb24 / fr24 grabbing the SDR due to misconfiguration.
When that happens, you could check
pgrep -af dump
That should show potential other programs using the SDR, well at least those that have dump in their name.
