Sentry Crash Report:

Description Richard Homonnai 2019-10-25 17:57:29 UTC 
Application: plasmashell (5.16.5)

Qt Version: 5.12.5
Frameworks Version: 5.60.0
Operating System: Linux 4.19.72-gentoo-richBOOK x86_64
Distribution: "Gentoo Base System release 2.6"

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

Closing Spotify after a longer session. The bug seems time-related, as it cannot be reproduced by simply retrying. Then, after some hours, next time it will crash again.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Plasma (plasmashell), signal: Segmentation fault
Using host libthread_db library "/lib64/libthread_db.so.1".

I'm pretty sure this has already been fixed, but can you please check in either Plasma 5.18 (the current LTS version) or Plasma 5.21 (the latest released version)? Thanks!

I don't know about 5.21.2 (it's not yet stable on Gentoo amd64)

but it hasn't happened for a long time, I can confirm it fixed with my current version (5.20.5) however. So from my viewpoint this bug can be closed, thank you :)

Cool, thanks for the info.
