Application: kdeconnectd (21.12.1) Qt Version: 5.15.2 Frameworks Version: 5.90.0 Operating System: Linux 5.16.1-1-default x86_64 Windowing System: X11 Distribution: "openSUSE Tumbleweed" DrKonqi: 5.23.5 [KCrashBackend] -- Information about the crash: - What I was doing when the application crashed: Kdeconnectd crashes intermittently but repeatably during normal usage of the desktop, not interacting with the software directly. Crash possibly coincides with a notification on the phone but am not completely sure on the timing. Also having issues with intermittent Android app crashes so it is possibly some kind of interrupted communication. Android app version 1.18.1 from Google Play Store The crash can be reproduced every time. -- Backtrace: Application: KDE Connect Daemon (kdeconnectd), signal: Segmentation fault Content of

Created attachment 147150 [details] New crash information added by DrKonqi kdeconnectd (21.08.1) using Qt 5.15.2 - What I was doing when the application crashed: I have connectivity report plugin enabled. - Additional info This phone is a XiaoMi POCO F3, which supposed to have 2 SIM card slots. In my configuration I only have 1 台灣之星==TSTAR SIM card inserted and the preferred network type is set to "NR/LTE/GSM/WCDMA" in the hidden modem settings activity. Since I only have a 4G subscription I only get LTE/4G(+) in the signal icon in the notification bar. -- Backtrace (Reduced): #4 0x00007f1ef11201e4 in (anonymous namespace)::constData (d=...) at kernel/qvariant.cpp:361 #5 qVariantToHelper<QMap<QString, QVariant> > (handlerManager=..., d=...) at kernel/qvariant.cpp:2669 #6 QVariant::toMap (this=0x55a019382b18) at kernel/qvariant.cpp:2721 #7 0x00007f1ee86f17a8 in ConnectivityReportPlugin::receivePacket (np=..., this=<optimized out>) at ./plugins/connectivity-report/connectivity_reportplugin.cpp:44 #8 ConnectivityReportPlugin::receivePacket (this=<optimized out>, np=...) at ./plugins/connectivity-report/connectivity_reportplugin.cpp:40
- Additional additional info * In the hidden modem configuration activity the SIM card slot is presented as "Phone 0". * The phone is running Android 11 based MIUI 12.5.7 Global based stock firmware
- Workaround Disable the connectivity report plugin (assuming any side(mobile/pc) would do, though I disabled both sides).
