Fwiw, this commit should fix this issue:

*** Bug 356595 has been marked as a duplicate of this bug. ***
Comment 3 kramski 2015-12-21 10:55:43 UTC 
Same here (Arch Linux).

KAddressbook (5.1), KOrganizer (5.1) and Kontact crash on exit, too.
Comment 4 Martin Schnitkemper 2015-12-21 22:01:05 UTC 
KMail crashed here on exit, too.  After I applied the patches from https://quickgit.kde.org/?p=kdepimlibs.git&a=commit&h=c6bf33a9018587e96a350bfd0b2bffde1859db27 and re-compiled the kdepimlibs I could exit KMail without a crash.  Seems that it works for me (Arch Linux)
Comment 5 Freddie Chopin 2015-12-21 22:21:31 UTC 
Same crash on Arch Linux with new version of kmail. Additionally sometimes I see crashes of akonadi resources for IMAP accounts when closing the system.
Comment 6 Martin Schnitkemper 2015-12-22 22:00:10 UTC 
Has already been patched & fixed for Arch users.
Comment 7 Freddie Chopin 2015-12-22 23:11:17 UTC 
Thanks for the heads up - I updated the system and it indeed works fine with the patches Arch maintainers applied.
