Description Pieter David 2018-09-03 11:21:07 UTC

Application: akonadiserver (5.9.0)

Qt Version: 5.11.1
Frameworks Version: 5.49.0
Operating System: Linux 4.18.5-arch1-1-ARCH x86_64
Distribution: "Arch Linux" (akonadi 18.08.0-1 package recompiled for debug symbols)

-- Information about the crash:
- What I was doing when the application crashed:
It's hard to say what triggers the crash, other than "kmail activity" (mail sync, browsing email folders). The frequency goes down when I set my gmail account to "offline", but it still happens from time to time.

- Custom settings of the application:
I have several IMAP accounts, two of which (one gmail, one work-related which uses a microsoft exchange server) have quite a lot of messages.

The crash can be reproduced sometimes.

-- Backtrace:
Application: Akonadi Server (akonadiserver), signal: Segmentation fault
Using host libthread_db library "/usr/lib/libthread_db.so.1".

New crash information added by DrKonqi

akonadiserver (5.9.0) using Qt 5.11.1

- What I was doing when the application crashed:

Akondi crashes when I startup my machine within about 15 seconds of my logging in and opening my KDE Wallet, no matter what I do -- whether Kmail is open or not.

When I restart it, it runs for a while and crashes again. Every time I open Kmail and browse emails, it crashes within less than a minute.

Comment 2 Rui Zhao 2018-09-05 16:09:02 UTC

I can confirm this bug, though I'm not sure about the exact cause.

A few information from my side:

I upgraded to package akonadi 18.08.0-1 on 21 Aug, and `akonadiserver -v` is 5.9.0.
The crash happens from time to time (a few seconds to a few minutes) after upgrade (but never did before upgrade).

I have a gmail account, an outlook account and an office365 (through imap/smtp, not microsoft exchange) account configured. (Another machine has more accounts configured, including microsoft exchange.)
After upgrade and restart kde, there is a window for authenticating gmail account, and I followed the steps (though, it doesn't seem to make any difference). I deleted the gmail account afterwards, but the crash still happens.
Shrinking the number of accounts to 1 also doesn't make the problem disappear.

Comment 3 Wolfgang Bauer 2018-09-06 08:42:45 UTC

AFAICS it's the same backtrace as in bug#398282, so likely a duplicate of bug#397239 I think.
In that case, it should be fixed in 18.08.1 (to be released today)...

Comment 4 Pieter David 2018-09-06 19:00:33 UTC

Indeed, after updating to 5.9.1 (applications 18.08.1) the crashes are gone.

Comment 5 Wolfgang Bauer 2018-09-06 19:47:00 UTC

(In reply to Pieter David from comment #4)
> Indeed, after updating to 5.9.1 (applications 18.08.1) the crashes are gone.

Thank you very much for the confirmation.

But let's better mark it as duplicate then...
