Application: plasmashell (5.10.4) Qt Version: 5.9.1 Frameworks Version: 5.36.0 Operating System: Linux 4.10.11-1-userns-custom x86_64 Distribution (Platform): Archlinux Packages -- Information about the crash: - What I was doing when the application crashed: Changed output of one of Firefox' audio streams to network sink via System Settings -> Multimedia -> Audio Volume -> Applications. - Custom settings of the application: PulseAudio 10.0-3 is configured with two sinks: default local and module-tunnel-sink-new. Output of some applications is redirected to network, others output locally. Kernel is taken from AUR and should be vanilla kernel with usernamespace enabled (for unprivileged lxc) so should be irrelevant. The crash can be reproduced sometimes. -- Backtrace: Application: Plasma (plasmashell), signal: Segmentation fault Using host libthread_db library "/usr/lib/libthread_db.so.1".
