Scrolling + "Terminal bell" crashes pulseaudio

[Anders Trier Olesen]

If "Terminal bell" is enabled (in "Profile Preferences" > "General"), and I scroll fast in the output of e.g less to cause the "alert sound" to be played repeatably very fast, pulseaudio crashes.

From /var/log/syslog:

I have seen frequent pulseaudio crashes in 17.04, see bug #1675892. (Maybe this one is a dupe of that.)

gnome-terminal causing pulseaudio crash most definitely does not belong to gnome-terminal but to pulseaudio.

Please see if you can get a stack trace of the crash. I will try when I have time...

It's likely this crash is already listed in:
https://errors.ubuntu.com/?package=pulseaudio&period=year

How do i get a stack trace from pulseaudio?

I can't find it in /var/log/* nor in /var/crash/*.

It was only a loose request if you knew how, but you can read:

Status changed to 'Confirmed' because the bug affects multiple users.

[Egmont Koblinger (egmont-gmail)]

Filed VTE feature request to rate limit the bell: https://bugzilla.gnome.org/show_bug.cgi?id=790815.

That being said, a pulseaudio crash is a pulseaudio crash which should be fixed in pulseaudio.
