This has happened several times before. Phone os: android 11 aosp, kde connect downloaded from f-droid, all up to date. The reporter is unsure if this crash is reproducible. -- Backtrace: Application: KDE Connect Daemon (kdeconnectd), signal: Segmentation fault [New LWP 1743] [New LWP 1773] [New LWP 1794] [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". 0x00007fdea0fea9cf in __GI___poll (fds=0x7ffe84a693b8, nfds=1, timeout=1000) at ../sysdeps/unix/sysv/linux/poll.c:29 __preamble__ [Current thread is 1 (Thread 0x7fde9d2272c0 (LWP 1712))] Thread 4 (Thread 0x7fde99571700 (LWP 1794)): #0 0x00007fdea0fea9cf in __GI___poll (fds=0x7fde90004a60, nfds=1, timeout=-1) at ../sysdeps/unix/sysv/linux/poll.c:29 #1 0x00007fde9f95136e in ??

Created attachment 151130 [details] New crash information added by DrKonqi kdeconnectd (22.04.3) using Qt 5.15.5 This happens sometimes when my phone disables wi-fi to keep energy. Unfortunetly, this behaviour cannot be controlled. It would be great to add some bypass mechanism to keep trying to reconnect or send event to phone without segfault. -- Backtrace (Reduced): #5 0x00007f75b4dee2d0 in QSettings::beginGroup(QString const&) () from /usr/lib/libQt5Core.so.5 #6 0x00007f75b62d72fc in KdeConnectConfig::getDeviceProperty(QString const&, QString const&, QString const&) () from /usr/lib/libkdeconnectcore.so.22 #7 0x00007f75b62c61ca in LanLinkProvider::configureSslSocket(QSslSocket*, QString const&, bool) () from /usr/lib/libkdeconnectcore.so.22 #8 0x00007f75b62cf6b6 in CompositeUploadJob::newConnection() () from /usr/lib/libkdeconnectcore.so.22 [...] #10 0x00007f75b45fa1c8 in QTcpServerPrivate::readNotification() () from /usr/lib/libQt5Network.so.5
