Title:
pulseaudio crashed with SIGSEGV in _IceTransClose()
Status in PulseAudio:
Unknown
Status in pulseaudio package in Ubuntu:
Fix Released
Status in pulseaudio source package in Impish:
Fix Released
Bug description:
* Impact
The pulseaudio service sometime segfaults on session closing which
trigger a bug report dialog
* Test plan
Log out of a desktop session and back in, there should be no error
prompt
The issue isn't triggered only randomly it seems so it might be easier to
check that reports stop on
https://errors.ubuntu.com/problem/877172e07ed9f86b0674cd458a5aaf24b37fb01e
* Where problems could occur
The change is in the X session closing handling so shouldn't impact on
normal use, if incorrect the fix could lead to increase the chance of
hitting the segfault when an Xsession is closed
