Description Thorsteinn A. Malmjursson 2012-01-23 18:22:45 UTC

Application: kmail (4.7.3)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-15-generic i686
Distribution: Ubuntu 11.10

-- Information about the crash:
I had just completed a mail check, and clicked on the first of the emails I'd received to open it - 2 or 3 windows opened concurrently, kmail hung and died.

The crash can be reproduced some of the time.

-- Backtrace:
Application: KMail (kmail), signal: Segmentation fault

Comment 1 Laurent Montel 2012-01-23 18:24:40 UTC

Reproductible ?

Comment 2 Thorsteinn A. Malmjursson 2012-01-23 21:09:32 UTC

Occasionally, Laurent, one out of every 7 or 8 opens results in this happening.  It's not all of the time, but happens some of it.

Comment 3 Denis Kurz 2016-09-24 18:01:16 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 kmail2 (version 5.0 or later, as part of KDE Applications 15.12 or later), it gets closed in about three months.

Comment 4 Denis Kurz 2017-01-07 21:31:54 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.
