Application: kdeconnectd (21.12.1) Qt Version: 5.15.3 Frameworks Version: 5.90.0 Operating System: Linux 5.13.0-28-generic x86_64 Windowing System: X11 Distribution: KDE neon User - Plasma 25th Anniversary Edition DrKonqi: 5.23.5 [KCrashBackend] -- Information about the crash: - What I was doing when the application crashed: Simply waking a mobile device that is paired (which presumably wakes KDE Connect on the device) crashes kdeconnectd. I do get the occasional crash on startup but this happens more often. This usually occurs regardless of what applications are running, but the crash happens almost immediately after waking a paired device. Doesn't happen every time, but has happened enough to be notable. I am on KDE Neon, but this sometimes happens on stock Ubuntu as well. The crash can be reproduced sometimes. -- Backtrace: Application: KDE Connect Daemon (kdeconnectd), signal: Segmentation fault [New LWP 6028] [New LWP 6029] [New LWP 6030] [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". 0x00007fc85e64eaff in __GI___poll (fds=0x7ffde49594b8, nfds=1, timeout=1000) at ../sysdeps/unix/sysv/linux/poll.c:29 __preamble__ [Current thread is 1 (Thread 0x7fc85a8992c0 (LWP 6027))] Thread 4 (Thread 0x7fc8521af700 (LWP 6030)): #0 0x00007fc85e64eaff in __GI___poll (fds=0x7fc844004a60, nfds=1, timeout=-1) at ../sysdeps/unix/sysv/linux/poll.c:29 #1 0x00007fc85cfc236e in ??
