Description Chris Samuel 2014-01-06 11:27:56 UTC

Application: kontact (4.12)
KDE Platform Version: 4.12.0
Qt Version: 4.8.4
Operating System: Linux 3.11.0-14-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:

I had told Kmail to autodetect the linux-btrfs mailing list information and it had seemed to be taking a while to process the folder (which has a lot of email in it), so I went away for an hour or so to do some shopping.   On my return it had crashed.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault

Comment 1 Denis Kurz 2016-09-24 19:25:19 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 2 Denis Kurz 2017-01-07 22:09:30 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.
