Did you update your Frameworks or Qt version without restarting? It appears to print an error on console, can you check your ~/.xsession-errors file for errors when the thumbnailer crashed? Nope, with an upgrade as impactful as that, I always reboot. That was nearly 2 weeks ago. pacman on Nov 13, and a reboot maybe an hour later. The next pacman was a package install, no reboot needed, and none since then. I think that is the second time recently that I've encountered someone mentioning ".xsession-errors". I think the other was relating to Kodi crashing. There is NO such file in ~/. It sounds like something I should be having, only if related to xorg stuff. Mind you, I can create such a crash at-will (as long as I don't reboot I'm sure), so if there's some test or "$ gdb -p" you want me to try, let me know. Oh, HEY! I just did "$ lsof" and grepped for "session" and found "/home/username/.local/share/sddm/xorg-session.log". I don't know if that's of interest. ***** kdeinit5: Got EXEC_NEW '/usr/lib/qt/plugins/kf5/kio/thumbnail.so' from launcher. kdeinit5: preparing to launch '/usr/lib/qt/plugins/kf5/kio/thumbnail.so' No protocol specified kdeinit5: PID 3054875 terminated.

Interesting that uptime is also showing 12 days again.
For what it's worth, I'm also seeing:

*****
I'm currently looking to see if I can re-establish X11 (even though I'd think it was running considering I'm typing this on the system).
I've no idea if this any way relates to when I turn on/off my receiver which I have HDMI going to, as well as DVI going to my monitor (don't ask, screwy monitor doesn't play nice with HDMI).
I also noticed a kernel trace log containing "i915" nearby.
I'll build a newer kernel (5.3.7->5.4.1 I think), reboot, keep an eye out for that error and report it if needed.
In any case, exceptions are being thrown and not caught and nicely notifying the user.
I missed that it started happening again on the 21st. And there was no issue with "kglobalaccel5" ever since the reboot, so that seems to be unrelated. So too is me turning on/off my receiver. There has been no issue for over 1 week after I did that as a test. Looking at the journal in verbose output, I saw a reference to /home/username/.local/share/sddm/xorg-session.log (also mentioned in my previous comment) which contained: ***** ...

Searching on this issue, I see it's been mentioned in the middle of the year: https://alien.slackbook.org/blog/kde-plasma5-for-slackware-introducing-qt-5-13-in-the-july19-update/#comment-36118 https://bugs.archlinux.org/task/63280 https://forum.manjaro.org/t/cant-run-apps-by-right-clicking-any-file-in-dolphin/85215 Even in 2015: https://bbs.archlinux.org/viewtopic.php?id=204835 And again starting today, where the previous update was done on the 27th last month. I see that kio-extras and ffmpegthumbs was both updated then and I see an update for them again today (19.12.1-1) which I'll do in a moment, but still there hasn't been any change as of yet. The error messages point to a setup problem. Qt crashes (i.e. shows a fatal error message), because it cannot find a platform plugin. I don't think you can expect help for this issue if it cannot be reproduced reliably; it might even be a hardware bug. "setup problem"? As in the installation? Or kdeinit5/thumbnail.so "setting up" to use QT stuff? If the issue was random in the sense that it would start to fail within 5 hours of a reboot one time, and then 29 days after another reboot, I would be more apt to agree with you on the "reliability" of the issue being produced... But when it is happening pretty regularly around 11 days, even when my usage varies, I'd call that pretty reliable. I can tell you that I just upgraded today after seeing the coredump entries starting on Feb 3rd, and the last time I upgraded/rebooted was on Jan 24th. That would make it like 11 days. I WOULD say it is not ideal in debugging/troubleshooting when you have to wait that long for the issue to rear its ugly head. I could always attach gdb to the process on like the 10th day and get a backtrace or some variable data sampled at that time to see if something is on its way out of bounds (about to cause it to freak out continually on the #th day), but I'd need a bit more guidance of what is to be expected from me (specifics, rather than the vague procedure I laid out) in doing this. I'd be curious to know how you could see hardware affecting ONLY this particular software in this manner (repetitive failures after #days). What files does kdeinit5/thumbnail.so affect (config?) that I could possibly just try renaming to get a fresh start (without just fully reinstalling everything). I think it would be obvious to say that thumbnail.so would create thumbnails for files, but I doubt I would need to delete the thumbnail cache (which would also be fine) since the issue isn't the display of thumbnails since it still does, but rather the creation of NEW thumbnails after #days. It's still an issue, but at least program address locations are being displayed in the dump: ***** Stack trace of thread 1806553: #0 0x00007bfb41f0e615 raise (libc.so.6 + 0x3d615) #1 0x00007bfb41ef7862 abort (libc.so.6 + 0x26862) #2 0x00007bfb421299ac _ZNK14QMessageLogger5fatalEPKcz (libQt5Core.so.5 + 0x8f9ac) #3 0x00007bfb4271c546 _ZN22QGuiApplicationPrivate25createPlatformIntegrationEv (libQt5Gui.so.5 + 0x131546) #4 0x00007bfb4271c9e1 _ZN22QGuiApplicationPrivate21createEventDispatcherEv (libQt5Gui.so.5 + 0x1319e1) #5 0x00007bfb423523e6 _ZN23QCoreApplicationPrivate4initEv (libQt5Core.so.5 + 0x2b83e6) #6 0x00007bfb4271fa20 _ZN22QGuiApplicationPrivate4initEv (libQt5Gui.so.5 + 0x134a20) #7 0x00007bfb4170b68a _ZN19QApplicationPrivate4initEv (libQt5Widgets.so.5 + 0x15e68a) #8 0x00007bfb42f04dfc kdemain (thumbnail.so + 0x6dfc) #9 0x00005ccbe71735bd n/a (kdeinit5 + 0x75bd) #10 0x00005ccbe7174a59 n/a (kdeinit5 + 0x8a59) #11 0x00005ccbe717521d n/a (kdeinit5 + 0x921d) #12 0x00005ccbe7170b54 n/a (kdeinit5 + 0x4b54) #13 0x00007bfb41ef9152 __libc_start_main (libc.so.6 + 0x28152) #14 0x00005ccbe71716be n/a (kdeinit5 + 0x56be) ***** kio-extras/dolphin version: 20.08.1 Testing this further (instead of just rebooting), I found that killing the kdeinit5 threads "file.so", sets things back the way it should (no crashes, thumbnails are generated). I first suicided kdeinit5. Then ps showed the previous, along with new instances existed as well as the "file.so" threads: ***** $ ps -ef |grep kdeini userName 1298 1 0 Dec03 ? 00:00:00 /usr/lib/kf5/start_kdeinit userName 1300 1 0 Dec03 ? 00:00:01 kdeinit5: Running... userName 70978 1300 0 Dec03 ? 00:00:40 kcalc [kdeinit5] userName 1721649 1300 0 19:55 ? 00:00:00 file.so [kdeinit5] file local:/run/user/<uid>/klauncherknWPUc.1.slave-socket local:/run/user/<uid>/kded5iOYDAY.1.slave-socket userName 1721650 1300 0 19:55 ? 00:00:00 file.so [kdeinit5] file local:/run/user/<uid>/klauncherknWPUc.1.slave-socket local:/run/user/<uid>/kded5mmOANs.2.slave-socket userName 1721652 1 0 19:55 ? 00:00:00 kdeinit5: Running... ***** It was only after killing those 2 sockets did the crashes stop and thumbnails start generating again.

() ***** There are 2 processes of this type. There were 2 instances of plasmashell related to file.so (plasmashelluXvTgd.328.slave-socket), but they all went away. The constant that remains are the kded ones. Unchanging pids. Okay, using coredumpctl info, I see that the dumps are for the plasmashell and dolphin related file.so stuff. I don't know if there's an effective way of finding if the kded related ones are in there as well (there are A LOT). First test was to kill the latest kded related file.so (pid 1908). No effect, still crashes. Then the other kded one (1907). Also still crashes. Next, I killed each of the only other file.so stuff that were related to dolphin (kded ones were recreated). Still crashed on the dolphin instance was recreated. Next, with this 2 recreated kded instances, I closed Dolphin and waited until there were no other file.so instances. After re-opening dolphin and going to a folder with new pictures, there are more coredumps. This kind of coredump is at least quick, where I don't even notice a slowed system as it's being dumped. With dolphin closed, I killall for the remaining kded file.so instances. Now that there are no file.so instances, I open dolphin, go to the folder and it still crashes (odd). ****Okay, close dolphin, killall file.so, suicide kdeinit5, file.so sockets are recreated, open dolphin, go to folder... SUCCESS. Reminder to self, in next 10+ days when it starts crashing again, close dolphin, suicide kdeinit5, make sure no other file.so instances exist, open dolphin and check folder. Apparently just killing the file.so instances were not enough, kdeinit5 also has to be suicided.
