Package: kdeconnect Version: 1.3.3-2+b1 Followup-For: Bug #841762
Hello ! I've been quite surprised to find that this bug report was first filled in 2016 because I've only began experiencing it for about a week. Using testing I waited for a week to see if a fix would come. Now's the time for the BR. Here is what I get when I start kdeconnecd manually : ------8<------8<------8<------8<------8<------8<------8<------8<------ ~$ LC_ALL=C /usr/lib/x86_64-linux-gnu/libexec/kdeconnectd kdeconnect.core: KdeConnect daemon starting kdeconnect.core: onStart kdeconnect.core: KdeConnect daemon started kdeconnect.core: Broadcasting identity packet kdeconnect.core: Unserialization error: "unterminated string" kdeconnect.core: Unserialization error: "illegal value" kdeconnect.core: Fallback (1), try reverse connection (send udp packet) "Network unreachable" KCrash: crashing... crashRecursionCounter = 2 KCrash: Application Name = kdeconnectd path = /usr/lib/x86_64-linux-gnu/libexec pid = 467719 KCrash: Arguments: /usr/lib/x86_64-linux-gnu/libexec/kdeconnectd KCrash: Attempting to start /usr/lib/x86_64-linux-gnu/libexec/drkonqi from kdeinit sock_file=/run/user/1000/kdeinit5__0 [1]+ Stoppé LC_ALL=C /usr/lib/x86_64-linux-gnu/libexec/kdeconnectd ~$ %1 LC_ALL=C /usr/lib/x86_64-linux-gnu/libexec/kdeconnectd QSocketNotifier: Invalid socket 8 and type 'Read', disabling...

It's also sad that we can't strace which system call causes the crash nor use gdb (even without debugging information). ------8<------8<------8<------8<------8<------8<------8<------8<------ ~$ LC_ALL=C strace /usr/lib/x86_64-linux-gnu/libexec/kdeconnectd strace: test_ptrace_get_syscall_info: PTRACE_TRACEME: Operation not permitted strace: ptrace(PTRACE_TRACEME, ...): Operation not permitted +++ exited with 1 +++ ~$ gdb /usr/lib/x86_64-linux-gnu/libexec/kdeconnectd [...] (No debugging symbols found in /usr/lib/x86_64-linux-gnu/libexec/kdeconnectd) (gdb) run Starting program: /usr/lib/x86_64-linux-gnu/libexec/kdeconnectd warning: Could not trace the inferior process. warning: ptrace: Operation not permitted During startup program exited with code 127. ------8<------8<------8<------8<------8<------8<------8<------8<------ I Recently made some modifications to iptables and sysctl as I wanted to improve my system security. I reverted my iptables configuration and it seems to be related with the sysctl knob net.ipv6.bindv6only. When set to 1, kdeconnectd crashes.
