Bug 392092

It seems that this crash occurs only if you start kontact right after computer startup. If you start it after a while, the crash does not occur.

It now seems to happen every time. Crash information:

what kind of partition is that ? does your user have write access to ~/.config/akonadi* and ~/.local/share/akonadi ?

Any error in the dmesg output ?

It's all under my home folder, I have access to everything (although I redid it, just to make sure...).
Again, the error is not reproduced if I stop kontact/akonadi and later restart it. It just happens the first time after booting up the machine.

No connection to opening kwallet at first time after login either, I just closed my wallet and let akonadi reopen it (with password etc.)

starting akonadi via akonadictl start does not produce any errors in konsole. Starting kontact in konsole will produce the same "Cannot rename log file - running on a readonly filesystem maybe?" error.

more testing:
starting kmail from konsole will render the same error.
starting korganizer from konsole will crash akonadi_control, but with a different error:

I have the same experience. I think it started from the moment I installed plasma 5.13 on my system. I'm using KDE Neon user build.

After starting up kmail I get this grey screen. But I can access the settings. When I start the account-wizzard from there after a while the akonadi self-test starts. And again it says that "akonadi is not registered at dbus".

I installed a package called mariadb-server and it seems as if things are better now.

Martin, could you please add the Konsole output? It should show which files it fails to rename, and why.

Same here with gentoo amd64, akonadi version 5.10.3
I was able to get a konsole output that tells the log file name when I start kmail for the first time after reboot:

the log files are in my home folder and there are no access restrictions for my user for the folder or the files. I can rename or delete the files manually without error messages.
It looks to me like the deletion of the .old file is not done even if fileOld.remove() returns success, or if there is some kind of race condition (this is all wild guess).

Also reported here:

I can confirm the crash on every start with akonadi_control 5.11.2:

Cannot remove old log file '%s': %s") at global/qlogging.cpp:887

Fix race-condition on akonadi_control start

Summary:
Check that there are no other akonadi_control instances running as the
very first thing on startup. Previously this check would happen after
AkApplication initialization, which contains some potential race-
conditions, like rotating log files.

The situation when akonadi_control is launched multiple times can occur
on session startup, when multiple different components will attempt to
launch Akonadi if its not yet running.
