Thanks for the instructions, Daniel! I found no crash files either locally or online, so I’ve implemented the workaround now, and will try to trigger the crash again.
For future reference, this was probably Ubuntu bug #1875558 (”libproxy1-plugin-gsettings triggers a lot of warnings”).
Since upgrading to 20.04 and switching to Wayland, Gnome terminal occasionally crashes. I interpret the corresponding logs to mean that it’s actually Wayland that fails to do something in the background, which then takes down Gnome terminal:

I have yet to nail down the precise circumstances, as this has (so far) been somewhat rare, having occurred perhaps once or twice a week.
Since the log mentions pointer, I should perhaps mention that I’ve set `org.gnome.desktop.wm.preferences` > `focus-mode` to `mouse`. Gnome terminal also exhibits other misbehaviour wrt. to this, occasionally refusing to get focus, or alternatively losing the focus, despite mouse cursor being over the terminal window.
Boinc-client logs ”No protocol specified” incessantly, twice every second on my setup.

With `media.autoplay.enabled.user-gestures-needed` set to false and `media.autoplay.default` set to 1 (block audio), which is the default (and other autoplay-related settings in their defaults as well), a Twitch video can only be either paused or playing muted; unmuting the video pauses it and vice versa.
== Steps to reproduce ==
1. Open about:config
2. Search for autoplay in the settings
3. Set media.autoplay.enabled.user-gestures-needed to false
4. Set media.autoplay.default to 1
5. Open a Twitch VOD, for instance https://www.twitch.tv/videos/280106033
6. Try to unmute the video
== What happens ==
The video is unmuted, but also paused
== What I expect to happen ==
For the video to continue playing, unmuted
I’m able to reproduce this when I set media.autoplay.enabled.user-gestures-needed
to false
; if set to true
(which is the default), unmuting does not pause the video.
Affected version
I’m using Ubuntu 20.04 and Wayland, with gnome-shell currently at version 3.36.1-4ubuntu1. (I originally filed this on Launchpad.)
Bug summary
When trying to start a virtual machine with Gnome Boxes, I get a prompt about keyboard shortcuts. The prompt text is localized, but translated back to English it says:
Boxes wants to inhibit shortcuts
You can restore shortcuts by pressing Super+Escape.
In my locale (Finnish), it says
Sovellus Boksit haluaa rajoittaa pikanäppäinten toimintaa.
Voit palauttaa pikanäppäinten toiminnan painamalla Super...
(sic; see attached photo)
So the actual key combination is truncated, defeating the point of that part of the text.
This isn’t a localization error (AFAICT, based on the translation source). Rather, it’s caused by the text being forced to fit on a single line of an arbitrarily fixed width, instead of wrapping to span as many lines as needed.
Screenshot
Still present in 20.04 (Focal) with vlc 3.0.9.2-1, though here at least it seems to only affect some URLs, not all. When I view a stream from my local webcam, vlc -vvv in the terminal shows
main playlist debug: incoming request – stopping current input
as the final message, and does not exit (after closing the window; Ctrl-Q still works). But when streaming from Wowza’s RTSP test stream [1], vlc exits just fine after closing the window.
Debian bug 916595 [2] and related VLC ticket [3] mention disabling hardware acceleration as a workaround, but even so I was unable to make it work (i.e. exit properly).
Possibly related: Ubuntu bug #1847162. There’s also been discussion about the issue over on Manjaro forums [4].
