[Seth Arnold (seth-arnold)]

Thanks for taking the time to report this bug and helping to make Ubuntu better. We appreciate the difficulties you are facing, but this appears to be a "regular" (non-security) bug. I have unmarked it as a security issue since this bug does not show evidence of allowing attackers to cross privilege boundaries nor directly cause loss of data/privacy. Please feel free to report any other bugs you may find.

[Daniel van Vugt (vanvugt)]

Dropped severity. This is the oldest supported Ubuntu release and I can't find evidence of the same crash on errors.ubuntu.com

[Daniel van Vugt (vanvugt)]

Incomplete. I think this was fixed or never reoccurred after 14.04. I can't find any other reports of it.

[Expired for pulseaudio (Ubuntu) because there has been no activity for 60 days.]

[MOZGIII (mozgiii)]

I just got the same issue at Ubuntu 18.04

[Daniel van Vugt (vanvugt)]

This crash doesn't seem to make the top 100 crashes in pulseaudio on 14.04 or 18.04. So that means I can't yet find it on errors.ubuntu.com :(

MOZGIII, do you have any more information you can share? Like a link to your crash on errors.ubuntu.com?
