New crash information added by DrKonqi

korganizer (4.13) on KDE Platform 4.13.0 using Qt 4.8.6

Looks like this crash still happens on exit with KDE 4.13.

Comment 2 Matthew Flaschen 2014-08-05 08:34:30 UTC

Application: korganizer (4.12.4)
KDE Platform Version: 4.13.3
Qt Version: 4.8.6
Operating System: Linux 3.14-1-amd64 x86_64
Distribution: Debian GNU/Linux testing (jessie)

I have similar symptoms, and the backtrace (attached) looks similar.  Every time I exit KOrganizer, it crashes.  I have multiple calendars, including some from an old system (this system is a fresh install with a restored home directory).

Comment 4 Denis Kurz 2016-09-24 19:25:59 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 5 Denis Kurz 2017-01-07 22:02:06 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.
