Summary: kdeconnectd CPU load at 100%
Classification: Applications
Product: kdeconnect
Version First 25.12.3
Reported In:

Full GDB backtrace
SUMMARY
kdeconnectd pegs a CPU core and cannot find any devices. Backtrace suggests
it's in some kind of strange clipboard polling loop. Judging by the backtrace
this is different from bug #486802 which has the same user-facing symptoms.
STEPS TO REPRODUCE
Unsure what action on my part triggered the issue, so I unfortunately cannot
provide reproduction steps.
OBSERVED RESULT
100% CPU usage, UI cannot find any devices.
EXPECTED RESULT
kdeconnectd runs with minimal CPU usage and enumerates devices.
