kontact (4.9.4) on KDE Platform 4.9.4 using Qt 4.8.2

- What I was doing when the application crashed:

Closed Kontact from the menu File->Exit/Quit.
Then a mesage box came up w/ a short message saying s/th like "Error when fetching mail".  It disappeared very quickly.

kontact (4.10.3) on KDE Platform 4.10.3 using Qt 4.8.4

- What I was doing when the application crashed:

Kontact was running slowly so I thought I'd quit and restart to see if that helped. I got a crash message.

Comment 3 Denis Kurz 2016-09-24 19:31:38 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 21:50:10 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.
