Description Justin 2022-06-24 02:02:06 UTC

Application: plasmashell (5.18.8)

Qt Version: 5.12.8
Frameworks Version: 5.68.0
Operating System: Linux 5.4.0-121-generic x86_64
Windowing system: X11
Distribution: Ubuntu 20.04.4 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Most frequently occurs when playing back video and/or audio, but not necessarily. The Discord application may or may not be related, also with multimedia, including images, but always most frequently with video/audio. Beyond that, no discernable reason or pattern to the crashes since sometimes they may even occur when the computer is idle and I'm away.
- Unusual behavior I noticed:
Beforehand nothing unusual is occurring, CPU, RAM, and disk well under the maximum stresses. After the crash, usually the screen halts, then goes blank or reverts to the computer manufacturer logo that appears during boot or simply goes black.
Once, every running program (including background and seemingly some drivers) crashed one by one or rather, the system could no longer "find them", but that seems to be a unique instance.
This appears to have been the only time it recovered from the crash.
- Custom settings of the application:
Several icons on the desktop, including some files. 3 sticky note widgets. 1 combo system load widget. 1 RAM & swap widget. 1 CPU widget. 1 weather widget. 1 KDE connect widget, default wallpaper.
- External hardware
System is installed on an external hard drive connected via USB. Also connected is a 4x USB hub, with a wireless mouse, an optical drive, and a floppy drive all connected.

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault

If you could get debug symbols for

it would help massively

These old versions are no longer supported or maintained. I would recommend that you upgrade to Plasma 5.24, which is provided in Kubuntu 22.04. It's likely the crash is already fixed in a newer version.

Couldn't find the exact location, but I attached the entire debug output just in case.

I already tried to upgrade the version a while ago before the crashes began, but couldn't get it to work, so I just stuck with this version.

Comment 7 Justin 2022-07-14 17:06:46 UTC

Updated to 21.10 (KDE 5.22.5), notice crashes may still occur, though far less frequently and abruptly. Again, no apparent pattern.
Will update with more information of what the crash looks like when it happens again.

Comment 8 Justin 2022-07-14 20:46:24 UTC

Confirmed crashes are different. Usually results in Plasma crashing, along with all programs, leaving a blank screen with only the mouse cursor. Keyboard inputs are still recognized, but attempting to open Konsole has a message stating that "it could not be found".
