Bug ID: 92780
Summary: Segmentation fault
Product: PulseAudio
Version: unspecified
Hardware: Other
OS: All
Status: NEW
Severity: normal
Priority: medium
Component: misc
Assignee: pulseaudio-bugs at lists.freedesktop.org

I'm experiencing a segfault in pulseaudio, which seems to happen when a
notification sound by GNOME or Skype is being played while I'm watching a movie
clip using the Flash plug-in in Firefox.
Core was generated by `/usr/bin/pulseaudio --start --log-target=syslog'.
Program terminated with signal SIGSEGV, Segmentation fault.
