            Bug ID: 363291
           Summary: Plasma crashed after audio device shutdown in
                    pulseaudio
           Product: kde
           Version: unspecified
          Platform: unspecified
                OS: Linux
            Status: UNCONFIRMED
          Keywords: drkonqi
          Severity: crash
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org
          Reporter: alexeyponomarenko92 at gmail.com

Application: plasmashell (5.6.90)
 (Compiled from sources)
Qt Version: 5.6.0
Frameworks Version: 5.22.0
Operating System: Linux 4.5.3-gentoo x86_64
Distribution: "NAME=Gentoo"

-- Information about the crash:
- What I was doing when the application crashed:
I went to audio settings GUI (pulseaudio) and disables one of the output
devices (build in audio adapter) after that plasma crashed. I had a USB headset
plugged in and detected by pulseaudio prior to that if it matters.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
