Sentry Crash Report:

Description Wolfgang Faust 2020-12-25 05:33:38 UTC 
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.

Just had something similar happen again. As the music was playing, this dialog popped up of its own accord:

> The server failed the authenticity check (search-alexanderstreet-com.ezproxy.sfpl.org).
>
> The issuer certificate of a locally looked up certificate could not be found
> No certificates could be verified

and when I clicked "Continue" Plasma crashed---this time without a DrKonqui popup, so I don't have a trace to provide.
