pulseaudio crashed with SIGABRT in pa_cvolume_set() from transport_speaker_gain_changed_cb() from pa_hook_fire() from rfcomm_io_callback() from dispatch_pollfds()

[Bor_Ed]

Same problems have been in avahi and systemd content recently.
Is 16.04 getting released in April and are these problematic and certainly buggy root daemons being removed in future releases of Ubuntu?

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.

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

I have the same problem when trying to add my bluetooth headset. It ends up adding it but can't connect to it afterwards. It disconnects. I have Ubuntu 16.04.

[Daniel van Vugt (vanvugt)]

Fix released after 17.04?...
