I remember having this issue as well on my computer. I think there is some incompatibility with running gqrx and having gr-osmosdr installed. What I did was simply uninstall gr-osmosdr to run gqrx then reinstall it when I need to use gnuradio with the rtlsdr source. I haven't had time to debug further though.
