Created attachment 134352 [details] Generating using the bug notice. I have several of these, they all report the same backtrace seg fault. I can send others. SUMMARY Kdeinit5 crashes every time I boot or restart my laptop. It is reported as my desktop is being initialized, running Kubuntu 20,04, Kernel 5.4.0-58-lowlatency, Plasma 5.18.5, Qt 5.12.8. A bug notification appears in my task bar, but it says it cannot be reported for this program. Aside from the boot bug, I occasionally will lose my wallpaper during the course of returning from a period of inactivity. Finally, I have also removed the splash in the startup/shutdown options, as it appeared to be associated with a complete freeze with only the cursor appearing. So far the freeze-up (requiring powering down) has not returned. STEPS TO REPRODUCE 1. Simply starting or restarting the computer 2. 3. OBSERVED RESULT A bug notice appears indicating KDEinit5 has crashed. I don't have any other observable results, although I occasionally will lose my wallpaper during the course of returning from inactivity (after screen suspends). I have removed the splash, as it appeared to be associated with a complete freeze with only the cursor appearing, after returning from sleep. So far the freeze-up (requiring powering down) has not returned since I have removed the splash. EXPECTED RESULT Rock-solid stability from my Linux box with no crashes or bug notices ;-) SOFTWARE/OS VERSIONS Windows: macOS: Linux/KDE Plasma: Kubuntu 20.04 (available in About System) KDE Plasma Version: Plasma 5.18.5 KDE Frameworks Version: 5.68.0 Qt Version: 5.12.8 ADDITIONAL INFORMATION see attachment

Created attachment 134586 [details] kdeinit5-20210105-141313-2ndcrash.kcrash.txt Hi Nate, First off, thanks so much for your prompt reply, you guys are amazing. I installed kio-extras-dbgsym, I'm hoping that is the debug package you recommended, following the info provided on the guidelines and howto pages. Could not find the kdelibs5-dbgsym mentioned on the page in the added repositories. If there is a package missing, please let me know how I missed it. I then restarted the computer and 2 crash reports were generated, they are attached.

Any chance you could upgrade to Kubuntu 20.10 and see if it still happens? 20.04 has software that's over a year old at this point.
Created attachment 134588 [details] attachment-31587-0.html Hi Nate, When I upgrade to the next LTS, I generally do a fresh install. I did one in the fall for 20.04, and have installed a fair bit of other things since then, so I'm reluctant to the fresh install. Do you think I can reasonably proceed with the upgrade approach without breaking too many things?

Kubuntu upgrades tend to be pretty stable so I imagine. But I can't promise anything of course. :) Oh, and be sure to have a backup!

I'm curious why the other posts (specifically older) "has been marked as a duplicate of this bug" I'd think the OG (first) post would be left alone and all of the others would've been considered duplicates. If you have an orange and put it in a replicator, the new orange is the duplicate, not the original orange.

On that version, line 315 is memcpy(shmaddr, img.bits(), img.sizeInBytes());. On master, it's line 306. I can try to compile kio and kio-extras from master, if needed.

Just had the thumbnailer crash again in the same code path with git master.
:( Méven, any ideas?
Confirmed crash here...even worse, usually leaves the panel (plasma) frozen for about 5 exasperating seconds. Fresh Install Arch Linux (5.10.27-1-LTS)
I didn't reproduce with neon unstable/dev (in a VM) with dpr 1, 1.75 and 2. I did vary a little the spectacle's copy to clipboard settings as well. With steps: 1. Launch Plasma 5.21.3 in a Wayland session 2. Set ctrl+PrtSc to launch org.kde.Spectacle RectangularRegion(true)) in SystemSettings' Custom Shortcuts (I used spectacle shortcuts settings) 3. Hit ctrl+PrtSc and select a region 4. A notification will pop up 5. Open the hamburger menu of the notification and select Copy (to clipboard) I also tested replacing step 3 with running "spectacle -rb" (region capture, background) Kai could you ensure you were running from master (maybe you forgot to reboot/logout ?) and spectacle as well, and could you send the stack trace you encountered if you still reproduce (and is different). Kabus > Confirmed crash here... What versions of KIO are you using ? The fix will be available in KDE Frameworks 5.81 but is currently only available in git / kde neon unstable.
I can confirm that applying patch from MR 376 helps. Bug is gone after it.

At first, I assumed it was because I had removed some images which appeared as thumbnails from my desktop, but I have other thumbnails there now and the problem is not appearing. I am very appreciative of the work that is being done and I have faith you guys will sort it out eventually.

I don't know if this helps however, like everyone else on the planet I have a key marked in two rows "prt sc" and "sysrq" so I've been using shift "prt sc" to take a screenshot. This causes kinit to crash I've just discovered that shift is not needed and then kinit doesn't crash.
as reported in *[Bug 435566] kdeinit5 crash* it's still happening after the latest updates the PrtSCr problem I never had and use it often often also restart or reboot of the PC is not necessary since kdeinit5 restarts itself

(In reply to Allexus J from comment #65) > Delete folder ~.local/share/baloo/ solved this problem. As @Méven stated above, I confirm this does NOT resolve anything. Besides, my issue was previously marked as duplicate to this issue, but I reported KDialog's Segmentation fault as well, which this bug report doesn't mention: https://bugs.kde.org/show_bug.cgi?id=436025 I hope it was intentional and the same patch should resolve both: KDialog and Kde5init issue.
I haven't seen this bug in a couple of weeks, so I believe it's been fixed in kio-extras 20.12.2. People sending new reports should ensure they're running at least this release.
I am running kio-extras 21.04.0 on OpenSUSE TW and I still have the problem, so I believe it has not been fixed. I have a few directories upon which it reproducibly crashes when I navigate to the directory in the fileselector from Qutebrowser. These directories have in common that they contain subdirectories with image files in them. However, if I begin individually removing files and subdirectories, it's no longer reproducible - e.g. I have a configuration where it crashes, I remove a subdirectory and it no longer crashes, I copy the subdirectory in again and it still doesn't crash. I don't know enough about how the thumbnailer works to come up with a reliable strategy to produce a minimal configuration. I can send a zip file of such a directory, however as it's rather large and contains sensitive files I would rather not post it online.
I can't reproduce the issue on my side (kio-extras 21.04.0-1, manjaro testing) anymore - i only encountered it when taking a screenshot that shows the thumbnail in a notification though. Are you sure your issues are related to this bug?

PreviewJob: Create a larger SHM when necessary It's possible that during the lifetime of a PreviewJob thumbnails with different sizes are created. The SHM was created to match the size of the first (non-empty) thumbnail, so any larger ones after that would reuse the SHM with insufficient size.

Hi Guys, Probably related. I experiment continuous crashes in kdeinit5 opening simple text files with kate. The crashes happen when (and only when) some particular pdf are in my home directory (for example this one: https://arxiv.org/pdf/2010.08895). Other pdf does not causes the crash. Also, Kwrite does not cause the crash, and if I move the "critical pdf" under a subdir of my home, even kate does not causes the crash anymore. I am on Manjaro stable, with latest updates (plasma 5.21.4, kde framework 5.81.0, kde apps 21.04.0) Hoping this help. Many thanks for your work on this wonderful DE.

You're welcome. You're not using either of the versions where this is fixed (listed in the "Version fixed in" field); closing again.
I simply want to thank you all, I've never participated in a bug resolution, but I've been a faithful Linux user since early Slackware days. Keep up the great work and glad it was fixed. Stephen
(In reply to vindicator from comment #19) > I'm curious why the other posts (specifically older) "has been marked as a > duplicate of this bug" Bug is resolved/fixed (and my curiosity upon seeing it referenced in the git logs is why I'm here) but I don't see that this question was ever answered. So here's my (explicitly unofficial as I'm just another bugfiler, here and elsewhere) attempt at an answer... There are (at least) two general bug-duplicate policies that can be employed by devs choosing which bugs to mark as duplicates. Some products or bug installations use one, some the other, and others may default to the first but choose the second given a strong enough reason on an individual bug basis. 1) Chronological order policy. Newer bugs are always duplicates of the oldest, original bug. This could be argued to be the most "correct", but often has the practical issue described/solved by the more pragmatic policy below. Still it's the most reasonable default in the absence of a solid reason to override and is thus favored where such priority-overrides are less common. In my experience distros commonly have this policy, probably because of their function as accumulators/packagers of software from various upstream sources. 2) Pragmatic "most useful information" policy. The "original" bug is defined as the one with the most useful information already posted to it at the time of the duplicate marking, regardless of which one was actually filed first. In my experience this policy is more common on upstream original software source providers, I'd suggest due to reasoning below, but extended to the more general case (that is, not always will the most informative bug-filing be the one with the commit-ID attached). Especially where (semi-)automated crash-report filing is used (as it is with some kde components and apps, with the user's consent of course), the often-automated chronologically first bugs may have very little additional information, while a bug filed later, sometimes only because its author took the time to collect and add additional information, has more practically useful information in terms of actually fixing the bug. A recent bug I filed where earlier bugs were marked duplicates of mine is a good example. For kde I run live-git versions built myself (using the gentoo/kde project's build scripts so it's pretty automated) and I normally update once or twice a week. I found a regression that wasn't there before my last update, so I checked the git logs to see what changed and then bisected the problem down to an individual commit. When I filed the bug it had the git commit ID that triggered the problem in the subject line. There was other information in the bug as well but honestly the commit ID was probably the most helpful and the reason earlier bugs were marked dupes of mine. But bisecting to an individual commit is a non-trivial amount of work and takes time. By the time I did that there were other bugs reporting the problem. But despite not being first, my bug was (presumably) considered to have more useful info attached, as I said, likely the commit ID alone was enough, so other bugs, including some filed earlier, were declared duplicates of mine.
(In reply to Flavio Cappelli from comment #88) > Hi Guys, > Hey Flavio, > Probably related. If you are not sure this sounds like a different bug, please open new bugs laser focused on your issue when you don't see duplicates with very close symptoms. Triagers and devs will mark them as duplicate if needed, but reporters can't do that and bugs reported as comments will very unlikely be fixed.

If you don't experience it with KDE Frameworks 5.82, it is not worth reporting/investigating anymore. > I experiment continuous crashes in kdeinit5 opening simple text files with kate.

Bug triaging is not a science and both triagers and reporters can make mistakes creating duplicates. Sometimes we peek earlier, sometimes best quality, sometimes just popularity or naming of the bug, there is no definitive rule, expect we want to limit the number of bugs, because a cacophony of bugs makes it harder to fix the bug, and harder for the bug reporters to see their bugs fixed. When we mark something as duplicate, triagers can copy over some data, and if he doesn't original reporters can copy or highlight it in the new main bug, I would encourage you to if you found value in it. You did some great job bisecting the origin of the bug, still the bug fix wasn't evident based on just that. Here the best stacktrace were sufficient to see approximately where the crash happened, and this was not sufficient to make the crash fix evident. With some effort, Fabian found it in the end.

No, I mean in dolphin, clicking with the left mouse button on a simple text file (I have kate as default text editor configured). Anyway, if I click with the right mouse button on the same text file, and choose "open with" -> "kwrite", kdeinit5 does not crash. >A crash without backtrace is really hard/impossible to fix. I know that, but unfortunately having debug symbols on Manjaro is not an easy task, expecially for a big software like KDE (see https://forum.manjaro.org/t/debug-symbols-on-manjaro/61157). >Seems it could be this bug though.

I will wait for framework 5.82 to arrive in Manjaro stable, and if the issue will still occur I will open a new bug report and try to provide a better backtrace. Regards Flavio

As the "Version Fixed Un" field says, this is fixed in Frameworks 5.82 and/or Plasma 5.22; you appear to have neither.
Thanks I am learning, very appreciate your comments and time.
