Description Roland Vet 2019-09-05 21:31:22 UTC

Application: plasmashell (5.16.5)

Qt Version: 5.13.0
Frameworks Version: 5.61.0
Operating System: Linux 5.2.11-arch1-1-ARCH x86_64
Distribution: "Arch Linux"

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

plasmashell crashes at log in/immediately when syncthingtray is installed/in the system tray widget.

No syncthingtray -> no crash

No system tray widget -> no crash
    Then adding system tray widget back -> crash

The crash can be reproduced every time.

-- Backtrace:
Application: Plasma (plasmashell), signal: Aborted
Using host libthread_db library "/usr/lib/libthread_db.so.1".

Also reported in the syncthingtray issue tracker [1] in case it's a problem on that end.

[1] https://github.com/Martchus/syncthingtray/issues/55

Comment 2 Nate Graham 2021-03-09 03:27:42 UTC

The crash does not appear to be in any KDE code. Does this still happen to you in either Plasma 5.18 (the current LTS version) or Plasma 5.21 (the latest released version)? Preferably when using the latest Qt version (5.15.2 or newer)?

Comment 3 martchus 2021-03-09 06:47:47 UTC

This has likely been fixed, see the GitHub issue. I can definitely not reproduce it on my systems anymore.

Comment 4 Nate Graham 2021-03-09 16:05:04 UTC

Cool, thanks.
