Description Jos van den Oever 2015-10-26 08:13:17 UTC

Application: kmail (4.14.10)
KDE Platform Version: 4.14.10
Qt Version: 4.8.7
Operating System: Linux 4.1.7 x86_64

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

I clicked on an unread mail in the list of mails in a subfolder of the inbox folder. I had read only one other mail since starting kmail.
This crash is repeatable every time by starting kmail and clicking on the same email.

- Unusual behavior I noticed:

KMail crashed.

mail that crashes kmail

Comment 3 Jos van den Oever 2015-10-26 09:15:08 UTC

This crash does not occur when the executable 'gpg' is installed.

Comment 4 Denis Kurz 2017-06-23 20:22:24 UTC

This bug has never been confirmed for a Kontact version that is based on KDE Frameworks, except possibly a Technology Preview version 5.0.x. Those versions differ significantly from the old 4.x series. Therefore, I plan to close it in around two or three months. In the meantime, it is set to WAITINGFORINFO to give reporters the opportunity to check if it is still valid. As soon as someone confirms it for a recent version (at least 5.1, ideally even more recent), I'll gladly reopen it.

Please understand that we lack the manpower to triage bugs reported for versions almost two years beyond their end of life.

Comment 5 Denis Kurz 2018-01-31 16:53:57 UTC

Just as announced in my last comment, I close this bug. If you encounter it again in a recent version (at least 5.1 aka 15.12, preferably more recent), please open a new one unless it already exists. Thank you for all your input.
