Hi folks, for over a year I've been using Kdeconnect without problems, but since last week's Android app upgrade, version 1.7.1, kdeconnect on my laptop would crash every 2-3 hours, or even less. The Android app shows then the following message: "this device is not connected /can't find any other device. Make sure it's connected to the same Wifi network", or something like that. In order to regain connection, I have to open the settings window on Linux and click on Refresh several times. After a few seconds, everything works again. Clicking Refresh on Android, or introducing my laptop's private IP, did nothing. I've tried downgrading the Linux package, but to no avail. Uninstalling and re-installing the Android app did nothing either. However, when I downgraded the Android app to the previous version (1.6.6) using APKMirror, the error disappeared until I upgraded it again. I'm using an up-to-date Antergos, with KDE Plasma 5.11.5, KDE Frameworks 5.42.0, and kdeconnect 1.2.1-1 (the same happens with kdeconnect 1.2-1). On Linux, journalctl shows the following message every time the crash happens: https://pastebin.com/raw/rsie5xPt Using Arch Wiki's article on core dump and debugging, I've created another two messages. They're very similar, but all this goes waaaay over my head, so I give you both of them in case it's useful for you: Doing "coredumpctl info 1289" https://pastebin.com/raw/JNVebVQJ Doing "coredumpctl gdb 1289" and then "bt": https://pastebin.com/raw/WU2SvkXL I hope that's enough for you guys to know what's wrong. As said, downgrading the Android app fixed it for a couple of days. I then upgraded it this morning to force a crash for this bug report, which happened few minutes later. Oddly enough, though, it's been several hours now and it hasn't crashed yet again. Thank you for your work!
I said on OP that it was taking too long to crash this time, as it usually takes only 2 hours, 3 tops. Well, it crashed again. I have absolutely no idea about any of this, but there are some new things, so in case you need more info, here is the backtrace: https://pastebin.com/raw/TefP2dqp
I can see that something happens, but not were this happens. It's hard to debug this without debug symbols. Can you recompile kdeconnect with debug symbols? There's instructions here, https://wiki.archlinux.org/index.php/Debug_-_Getting_Traces, but they may be a bit difficult to follow if you do not have any experience with compiling stuff. Also adding David Faure maintainer, since the crash happens in KIO code.
Thanks Matthijs. That's way over my head, but I'll give it a try as soon as I can.
Hi again, I compiled kdeconnect with debug symbols, following the Arch Wiki, but, with no experience on this whatsoever, I'm not sure if I did it correctly. My /etc/makepkg.conf has this line: OPTIONS+=(!strip docs !libtool !staticlibs emptydirs zipman purge !optipng !upx debug) The PKGBUILD I used to compile kdeconnect has this line: -DCMAKE_BUILD_TYPE=RelWithDebInfo \ After compiling for a few minutes, I got a 45 MB *.pkg.tar (instead of the typical ~500 KB for kdeconnect), which I installed. I then run: pkill kdeconnectd gdb /usr/lib/kdeconnectd (gdb) run After which the program works fine (clipboard, ping, some commands I added...). After some time I get the next message: Thread 1 "kdeconnectd" received signal SIGSEGV, Segmentation fault. However, neither "coredumpctl list" nor journalctl show anything. With previous installs, using the packages from the offical repos and without using gdb, there were messages about the segfault. In any case, kdeconnect on laptop doesn't even show my phone, and the Android app is still "connected" but clearly not working (no clipboard, commands don't work...). Back to gdb, I run: set logging file trace.log set logging on thread apply all bt full [several Enters to show the whole thing] set logging off quit [confirm exit with Y] I then open the settings on the laptop, refresh, and after a few seconds everything works again. Here is the commands I wrote and what the terminal showed: https://pastebin.com/raw/BeBv7S5G And here is trace.log, which if I'm not mistaken is exactly the same: https://pastebin.com/raw/1sCLgiGQ Once it was running again, I re-run gdb again, but this time not with "run", but with "start". It crashed after a few hours, but this time I did get a coredump. Here is the output of journalctl: https://pastebin.com/raw/BhvmrSg6 Here is the result of coredumpctl: https://pastebin.com/raw/rmXtdm5L Here is the trace.log I got from gdb, very short: https://pastebin.com/raw/d6NwrFM8 If I made any mistakes, please tell me and I'll try to fix it.
Should be fixed by: https://cgit.kde.org/kdeconnect-kde.git/commit/?id=6495e8dc538610fb679df0f1522243103a3a1789
Hi all, yesterday I upgraded kdeconnect on Android (1.8). Both yesterday and today I got the same problem again: after 2-3 hours it disconnects. Again, uninstalling and installing kdeconnect 1.6.6 fixes the problem. Since the old version is awesome enough, I think I'll stick to it.
Created attachment 115534 [details] crash coredump
I noticed that my coredump is different from the previous. Anyway, it happens only when receive notification plugin is turned on if it can help
P.S. this is the coredump when notification receive is on https://pastebin.com/1rKb2WX1

Might this be a duplicate of 427560? Dr. Konqi thinks that one matches my backtrace -- so it warned me to ignore the error unless I know for a fact that the information is needed -- but I wasn't using SDDM or logging out. What happened for me in real life was that I got a notification on my phone, and then I got a kdeconnect crash notification on my desktop. I Googled, and got https://bbs.archlinux.org/viewtopic.php?id=238636, which seems to match my experience, and that page referenced this bug. Since the status of /this/ bug is "needsinfo," I thought maybe it would be okay if I said something. I apologize if I really do have nothing of substance to offer. But I thought I'd chance it.
I'm having the same issue here. Now I can't get Connect or SMS to see each other on: Parrot OS 5.0 KDE Framework 5.78.0 Kernel 5.15.2-5parrot1-amd64 OnePlus 8T+ 5G Oxygen Dell Optiplex 7010 Win 10 **H2? None will see each other anymore.
