Has been present for months but I have not got around to debugging. I am fairly certain it happens due to html content of certain emails (crashes on opening or closing the email, but not predictable), which points the finger at Qt WebEngine? Andy.

Nice. I believe no multiple merge candidates happened here in quite a while. Last time it happened "Clear Akonadi Cache" did the trick. While I look forward to a new major upstream version of KDEPIM & Akonadi in Debian, I appreciate that you do some backports of fixes for stable users first. My major issue still are the Web Engine related crashes of KMail. KMail crashes several times a day during filtering here¹.

Okay, I thought there is just was multiple merge candidates issue which got worked around by the recent patchsets. Thanks, -- Martin

I actually have a backport in mind, for these patches, but before requesting this, the package needs to enter testing. It is possible to install the same packages on a stable system ( i tried it on a friends computer, who was hit by this issue), but this is NOT recommend! Because you loose the further upgrade path. I would recommend to wait for several days until the patch is available on Buster. Just for be more clear, the links are not correct, I fix this: https://phabricator.kde.org/D20243 https://phabricator.kde.org/D19487 > [1] Automatic recovery from Multiple Merge Candidates error > > https://phabricator.kde.org/D21455 did you tried this patch locally? > > [2] For some details see also "Common Infrastructure" in: > > March and April in KDE PIM > > https://www.dvratil.cz/2019/05/march-and-april-in-kde-pim/ okay this reference another patch I want to backport additionally: https://phabricator.kde.org/D19983 > [3] KMail: "Multiple Merge Candidates" error and how to fix it > > https://www.dvratil.cz/2017/01/kmail-multiple-merge-candidates-error-and-how > -to-fix-it/ that article is referring to another patchset, that was merged two years ago. signature.asc Description: This is a digitally signed message part.
Akonadi 4:18.08.3-6 automatically resolves mutiple merge candidates errors
Hi! Sandro kindly backported an important fix about the mutiple merge candidates issue from Akonadi 19.08 to 18.08¹ ². It does not fix the actual issue from happening, but it allows Akonadi to resolve the issue without user interaction³. The fix is currently available in Debian Sid. So if you have this issue from time to time and can use Debian Sid, please make sure you update. A fix for Debian Buster definitely seems possible now that Sandro backported the fix, however I do not know Sandro's plans there. It may very well be that the Akonadi packages from Debian Sid could just be installed in Buster, but I did not try this. In case it would break you would get to keep the pieces as usual :). On any account only try this if you are experienced enough with APT pinning and APT in general and have a backup. Thank you, Sandro!
