Comment 8 mail 2015-01-09 13:54:02 UTC

Same for me, but only whenever akonadi is installed! Without akonadi installed, everything works as expected but I cannot use kmail and so on, of course.

Comment 10 Denis Kurz 2016-09-24 20:44:58 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 11 Denis Kurz 2017-01-07 21:50:52 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.
