Git commit d9194563b17e567317fa3b533a0daa0b03e3fd4b by Allen Winter.
Committed on 22/01/2012 at 16:24.
Pushed by winterz into branch 'master'.

in mimeTypesMonitored() and itemsMonitored() don't call toList() on
empty QSets. Since QSets are QHashes and performing operations on
empty QHashes is crashy.

Comment 7 Denis Kurz 2016-09-24 20:39:45 UTC

This bug has only been reported for versions older than KDEPIM 4.14 (at most akonadi-1.3). Can anyone tell if this bug still present?

If noone confirms this bug for a recent version of akonadi (part of KDE Applications 15.08 or later), it gets closed in about three months.

Comment 8 Denis Kurz 2017-01-07 22:34:14 UTC

Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.0 aka 15.08), please open a new one unless it already exists. Thank you for all your input.
