akonadiconsole (0.99) on KDE Platform 4.11.1 using Qt 4.8.5

- What I was doing when the application crashed:

I used Akonadi Console for a while with Debugger and JobTracker enabled. I disabled them, closed Akonadi Console and got this crash.

korganizer (4.10.5) on KDE Platform 4.10.5 using Qt 4.8.4

- Unusual behavior I noticed:
when I opened another calendar in korganizer, started acting slow and deleted all of the entries in the new calandar. I did attach an .odt to one entry.

Comment 3 Denis Kurz 2016-09-24 19:30:09 UTC

This bug has only been reported for versions before 4.14, which have been unsupported for at least two years now. Can anyone tell if this bug still present?

If noone confirms this bug for a Framework-based version of kontact (version 5.0 or later, as part of KDE Applications 15.08 or later), it gets closed in about three months.

Comment 4 Denis Kurz 2017-01-07 22:41:57 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.
