            Bug ID: 90416
           Summary: [abrt] pulseaudio: pa_atomic_load(): pulseaudio killed
                    by SIGSEGV
           Product: PulseAudio
           Version: unspecified
          Hardware: Other
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: daemon
          Assignee: pulseaudio-bugs at lists.freedesktop.org

Changing the card profile via "set-card-profile" causes a crash in the
PulseAudio daemon when the echo cancellation module is active for a running
program with an open audio stream i.e. the program is started with:

export PULSE_PROP="filter.want=echo-cancel"

If the echo cancellation filter is not requested, then the set-card-profile
works fine.
