Description Dennis Schridde 2012-06-27 16:11:23 UTC

Application: kontact (4.8.4)
KDE Platform Version: 4.8.4 (4.8.4)
Qt Version: 4.8.2
Operating System: Linux 3.4.4-gentoo x86_64
Distribution: "Gentoo Base System release 2.1"

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

When I drag additional mails from the message list into the attachment area of a new mail dialogue, kontact crashes. I have to do this using alt+tab, because I cannot access the window-list plasmoid.

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Aborted
Using host libthread_db library "/lib64/libthread_db.so.1".

New crash information added by DrKonqi

kontact (4.8.4) on KDE Platform 4.8.4 (4.8.4) using Qt 4.8.2

Additional info: Happens only on the 2nd attachment. The first email I drag into the new-mail window is attached as expected.

Comment 3 Denis Kurz 2016-09-24 17:56:43 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 22:50:46 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.
