New crash information added by DrKonqi
kmail (5.9.3) using Qt 5.11.3
- What I was doing when the application crashed:
Okay, this happens also with KDEPIM/Akonadi 18.03.1 (all packages upgraded). Another backtrace attached.

I do not know why DrKonqi reduced the backtrace. It definately looked longer. Created attachment 117912 [details]

kmail (5.9.3) using Qt 5.11.3
- What I was doing when the application crashed:
Another backtrace. Let's see whether DrKonqi truncates this one as well. If it does, I will cut and paste the full backtrace in a moment.

Okay, on one hand DrKonqi does not thing the backtraces are related, on the other hand it truncates the backtrace when I tell it to add it to the bug report. Since I do not know whether DrKonqi got this right, this time I add the full backtrace manually: Application: KMail (kmail), signal: Segmentation fault Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

But this look fine and you have valid looking this=0x564f98590fb0. It looks like dvratil already said, like we try to access an already deleted item.

Did not like to crash so far, tough. Once it crashes, it is safe to send the valgrind log to the bugtracker regarding privacy? It currently is 2,1 MiB and it did not grow recently anymore.

second valgrind run, with error-limit=no
Second valgrind run:
valgrind --error-limit=no --track-origins=yes --num-callers=50 kmail &> 404052-kmail-valgrind.log
KMail actually crashed. It did not in the first run.
I also installed some additional debug packages, but I still missed some, as I was not aware of "find-dbgsym-packages" from Debian package "debian-goodies".
I am uploading in the hope that it may still be enough to pin-point the issue. I may have a go with all debug packages installed later this week, but for now I have enough of a KMail that is so slow it that I can see each rendering operation in slow motion.

third valgrind run, with all dbgsym package and crash
Another valgrind run. Hopefully this one is enough to find the issue.
This time I have all debug symbols installed.
https://bugs.kde.org/show_bug.cgi?id=405491 might be related, though no mail filtering needed (opening a few mails is enough) Thanks, Christian. Dan, could you have the look at the valgrind traces I produced? The third one would be the most accurate one, I believe. Dan, I just like to remind kindly. This regular crash together with a host of other issues add up and make the KDEPIM experience with KDEPIM/Akonadi 18.08 quite a bit less enjoyable than with previous versions. I do not have access to KDEPIM/Akonadi 18.12 as regular Debian packages yet and this likely will remain so until Debian 10 is released (Freeze). As far as it affects other users it would be important to get a fix into Debian 10. And yes, I know you do this in your spare time. But if you do not have time to look into the backtraces, would you please clearly say so, so I could try to find someone else to look into it? I likely will be mostly or completely offline from Friday to Monday, but after that I'd be able to answer any questions you may have. *** Bug 405878 has been marked as a duplicate of this bug. *** Thank you for reporting this crash in KDE software. As it has been a while since this issue was reported, can we please ask you to see if you can reproduce the crash with a recent software version? If you can reproduce the issue, please change the status to "CONFIRMED" when replying. Thank you! Dear Bug Submitter, This bug has been in NEEDSINFO status with no change for at least 15 days. Please provide the requested information as soon as possible and set the bug status as REPORTED. Due to regular bug tracker maintenance, if the bug is still in NEEDSINFO status with no change in 30 days the bug will be closed as RESOLVED > WORKSFORME due to lack of needed information. For more information about our bug triaging procedures please read the wiki located here: https://community.kde.org/Guidelines_and_HOWTOs/Bug_triaging If you have already provided the requested information, please mark the bug as REPORTED so that the KDE team knows that the bug is ready to be confirmed. Thank you for helping us make KDE software even better for everyone! I still see KMail crashing from time to time during filtering mails in a Maildir resource received by POP3 resource. KMail 5.21.0 (22.08.0) on Devuan Ceres with KDE Plasma 5.25.5, KF5 5.98.0 and Qt 5.15.6. I did not verify whether the back trace is similar as I saw bug reports regarding KDEPIM sitting in Bugzilla for ages and I am currently not convinced to spend time on it. I took a long time to provide quite a lot of accurate bug reports with a lot of details often with little result. However… if there is a developer willing to look into this bug then I am willing to invest time to create another back trace and answer further questions. (No offense meant. The situation is as it is.) |
