           Summary: pavucontrol crash at MainWindow::updateCard
                    (this=0x8264400, info=...) at mainwindow.cc:319
        QA Contact: pulseaudio-bugs at lists.freedesktop.org
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: rdieter at math.unl.edu
          Hardware: Other
            Status: NEW
           Version: unspecified
         Component: pavucontrol
           Product: PulseAudio

Since upgrade to pulseaudio-5.0, there seem to be cases where card profile
struct isn't fully initialized (name field particularly), so experience crashes
in applications that don't handle this.

Examples include: gnome-settings-daemon, gnome-shell ( see
http://bugzilla.gnome.org/732952 ) and pavucontrol (here).
