screenshot of the observed result

SUMMARY
When I launch console from the shell using arguments like
konsole --help
konsole --version

I get errors like these:
QThreadStorage: entry 8 destroyed before end of thread 0x555fa0013cc0
QThreadStorage: entry 4 destroyed before end of thread 0x555fa0013cc0
QThreadStorage: entry 3 destroyed before end of thread 0x555fa0013cc0

According to https://bugs.kde.org/show_bug.cgi?id=503421, this bug already existed and should have been fixed in QT 6.9. However, I have QT 6.10.0, and the bug is still present.

STEPS TO REPRODUCE
1. Run shell (in example, konsole)
2. write "konsole --version" or "konsole --help" in example
3. Get errors about QThreadStorage

OBSERVED RESULT
These errors are displayed after the main content.

EXPECTED RESULT
These errors are not displayed.

I can reproduce this with Qt 6.9.2, and also with the Flathub and nightly KDE Flatpak versions of Konsole.

Comment 2 Christoph Cullmann 2025-11-29 16:28:38 UTC

Can reproduce in master with recent Qt, too:

❯ konsole --version
qt.multimedia.symbolsresolver: Couldn't load pipewire-0.3 library
qt.multimedia.symbolsresolver: Couldn't resolve pipewire-0.3 symbols
konsole 26.03.70
QThreadStorage: entry 3 destroyed before end of thread 0x559b0ae59f60
QThreadStorage: entry 2 destroyed before end of thread 0x559b0ae59f60

Same for Kate, that seems to be still a generic issue.

❯ kate --version   
qt.multimedia.symbolsresolver: Couldn't load pipewire-0.3 library
qt.multimedia.symbolsresolver: Couldn't resolve pipewire-0.3 symbols
kate 26.03.70
QThreadStorage: entry 1 destroyed before end of thread 0x555ea6c78370
QThreadStorage: entry 0 destroyed before end of thread 0x555ea6c78370

Comment 3 Christoph Cullmann 2025-11-29 16:43:46 UTC

My Qt is 6.10.1.

Comment 6 Christoph Cullmann 2025-11-29 17:06:30 UTC

Could that be a side effect that --version exits perhaps in some bad way?
