knotify crash (sometime, not every time) when usb media remove, just system log in or deleting file if you use phonon-backen-vlc 0.8, 0.7 with vlc 2.1.5. backen-vlc 0.6 with vlc 2.0.10 work correcly. Reproducible: Sometimes
Please add the backtrace for the crash. For more information, please see https://techbase.kde.org/Development/Tutorials/Debugging/How_to_create_useful_crash_reports

Thanks for the update. Unfortunately, the backtrace does not reveal much information, but it looks like a double-free inside Phonon::MediaSource.
since i upgraded to vlc 2.20 and phonon-backend-vlc 0.8.5, have not occur.
and eglibc 2.17 bug, maybe releated with eglibc 2.13.
