Description Daniel Holgerson 2020-12-11 21:00:45 UTC

Application: plasmashell (5.14.5)

Qt Version: 5.11.3
Frameworks Version: 5.54.0
Operating System: Linux 5.9.0-12.1-liquorix-amd64 x86_64
Distribution: Debian GNU/Linux 10 (buster)

-- Information about the crash:
Fresh start of PC opened terminal. Left for 10 mins. On return saw a notification in tray of this crash. I'm on Debian Buster, therefore on an aged and tinkered with Plasma. This crash as well as the very few other I experienced are actually no crashes as I don't notice anything of it apart the bug-report. Can happily continue work as opposed to a total stand still on other systems. In conclusion:  I wouldn't want the devs or testers to funnel time to this non-issues of an outdated DE and ultimately be distracted from working on more current version.

The crash does not seem to be reproducible.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

I'm afraid Plasma 5.14 is over two years old and is no longer maintained. The latest LTS vesion is 5.18, and the latest non-LTS version is 5.20. 5.21 will be released in two months.

Please open a new bug report if you can reproduce the issue in either the latest LTS version, or the latest non-LTS version.

Also please lobby the Debian packagers to only package Plasma LTS versions. :)

Thanks for answering. This can be closed. I wasn't fully aware of the philosophy of debian stable (only security and bug fixes and only exceptional full updates of packages), but I can't say I'm missing much, apart from things like plasma. I fear the only considerable success in convincing the Debian maintainers of anything atm would be a made with metric tons of moneys.


tl;dr: I'll be submitting bugs again (or presumably not considering my smooth ride with 5.14), when I'm on a more recent Plasma version.

Have a great whatever it is you're celebrating with, the passing of the blessed year 2020. See 'ya.
