Application: plasmashell (5.20.4)

Qt Version: 5.15.2
Frameworks Version: 5.77.0
Operating System: Linux 5.4.0-58-generic x86_64
Windowing system: X11
Distribution: KDE neon User Edition 5.20

-- Information about the crash:
- What I was doing when the application crashed:

I was playing some music from a page in Firefox. (Plasma Integration 1.7.6, on Firefox 83.0.) This was a page loaded via my local public library's EZProxy, which caused Plasma to complain with a dialog box about a certificate error when the music started playing; I told it to continue anyway but keep the exception only for this session. I paused the music and later put the computer to sleep. Some time later I woke the computer back up, hit the play button on the lock screen (which started the music playing), and put my password in. After the computer unlocked, I saw the same certificate error dialog, and dealt with it in the same way as before. Immediately thereafter, Plasma crashed, and I couldn't hear the music any more, although the page was still playing. After it had automatically restarted I discovered that the headphone output was now muted; when I unmuted it the sound came back as expected.

I've tried a couple times to reproduce this by pausing the music again, putting the computer to sleep, waking it up, and hitting play on the lock screen; but I haven't gotten either the cert error or the crash.

The crash does not seem to be reproducible.
