SUMMARY Hi, whenever I put back in the case my Sony WF-1000XM4 (paired in HSP/HFP mode, with mSBC codec), it disconnects from my laptop Bluetooth and this causes a problem in pulse audio. Somehow consequently a crash is reported for KdeConnect Daemon. Follows backtrace (I recently updated from 22.04.1 LTS to 24.04 LTS) STEPS TO REPRODUCE 1. Pull the headphones out of the case and wait for them to connect via BT (already paired with HSP/HFP mode, with mSBC codec as default), they will initially connect as AD2P and later move to the preset I choose 2. Put the headphones back in the case OBSERVED RESULT A crash in KDEconnect Daemon happens and the mobile phone is not connecting no more to the daemon EXPECTED RESULT Kdeconnect continues working as before SOFTWARE/OS VERSIONS Operating System: Kubuntu 24.04 KDE Plasma Version: 5.27.11 KDE Frameworks Version: 5.115.0 Qt Version: 5.15.13 Kernel Version: 6.8.0-41-generic (64-bit) Graphics Platform: offscreen Processors: 16 × AMD Ryzen 7 PRO 6850U with Radeon Graphics Memory: 30.1 GiB of RAM Graphics Processor: AMD Radeon Graphics ADDITIONAL INFORMATION Application: KDE Connect Daemon (kdeconnectd), signal: Segmentation fault [KCrash Handler] #4 0x0000777f9a1c0607 in ??

I can't always reproduce but that happens frequently when I perform the steps described on the summary.
Unfortunately, the crash report is missing symbols. Could you please install debug symbols and attach a new symbolicated backtrace generated by using coredumpctl gdb in a terminal window? See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_using_coredumpctl for details about how to do this.
