Bug 513585

Application: kdeconnectd (25.12.0)

ApplicationNotResponding [ANR]: false
Qt Version: 6.10.1
Frameworks Version: 6.21.0
Operating System: Linux 6.17.12-300.fc43.x86_64 x86_64
Windowing System: Wayland
Distribution: "Fedora Linux 43 (KDE Plasma Desktop Edition)"
DrKonqi: 6.5.4 [CoredumpBackend]

-- Information about the crash:
This has been going on for a while now, it happens at startup and seems to keep happening when restarting KDE connect. After a while it seems to just work. I've been noticing segfaults when running openCL programs with mesa's rusticl too that seem related but may be fully unrelated. I also compiled a new release of mesa and that did not have the issue so I'm pretty sure these are unrelated.

The crash can be reproduced sometimes.

-- Backtrace:
