Andy,
Are you still having this problem? It seems way low-level, so it's
hard to determine what might have gone wrong in GNU Radio.

I know you said you didn't have automatic updates turned on, but
perhaps you updated recently in a way that required a computer restart
that you hadn't done immediately? A change to glib2.0 might request
that.

This might seem like an extreme measure, but it's the only one I can
think of based on your email. Can you just rebuild GNU Radio from
source and reinstall it?
