This time it was when I started playing a video on BBC News in Firefox using the Adobe plug-in. The sound still worked and the volume control in the browser plug-in continued to work. The crash can be reproduced some of the time. -- Backtrace: Application: KMix (kmix), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".
