Hi Stefan, I see this often enough too (in jessie) -- I have tried and failed to work out why.
One thing that does help is to clear the akonadi cache(s) for that resource -- it then stops crashing every few minutes and you can go back to having a usable kmail for a week or so before it starts crashing again. Run akonadiconsole → "Browser" tab → "Collection" tree → select folder in relevant IMAP resource → right click, "Clear Akonadi Cache" → repeat for other folders (I think) That it is always the same akonadi_imap_resource that crashes (it's only ever one of the 3 that I have) and that the problem comes back probably means it is one specific email that is the issue. I have no idea which one or how one would go about working out which one other than some sort of binary search of deleting emails and waiting a couple of weeks for crashes. cheers Stuart -- Stuart Prescott http://www.nanonanonano.net/ stu...@nanonanonano.net Debian Developer http://www.debian.org/ stu...@debian.org GPG fingerprint 90E2 D2C1 AD14 6A1B 7EBB 891D BBC1 7EBB 1396 F2F7
