Description mhdmatheen 2017-02-11 02:51:06 UTC

Application: kmail (5.4.2)

Qt Version: 5.7.1
Frameworks Version: 5.30.0
Operating System: Linux 4.4.0-62-generic x86_64
Distribution: KDE neon LTS User Edition 5.8

-- Information about the crash:
- What I was doing when the application crashed:
After installing KMail and MySQL, KMail crashes every time when opened.

- Unusual behavior I noticed:
When opening from terminal, these lines printed out:

~$: kmail
org.kde.pim.kidentitymanagement: IdentityManager: There was no default identity. Marking first one as default.
Could not find QtWebEngineProcess
*** KMail got signal 6 (Exiting)
*** Dead letters dumped.

KCrash: Arguments: /usr/bin/kmail

- Custom settings of the application:
I haven't changed any setting of the application. Just changed the couple of plasma themes. But I guess that's not the problem.

The crash can be reproduced every time.

Comment 1 Joshua J. Kugler 2019-12-31 00:06:30 UTC

This bug is going on three years, and I'm still hitting it.

I just installed Neon (neon-user-20191226-1116.iso). Logged in. Installed Kmail. Started it. New profile dialog came up, and then it put up a dialog box:

The Email program encountered a fatal error and will terminate now.
The error was:
Invalid parent

Letting KMail die, and starting it again seems to let it proceed, but it did fail on both fresh installs I tried.

Comment 2 Christoph Feck 2020-01-15 08:07:49 UTC

Joshua, do you get the same backtrace? The backtrace from comment 0 shows a crash in QtWebEngine, but the reporter used a Qt version that is now very old.

Comment 3 Hervy Qurrotul Ainur Rozi 2022-05-16 12:33:49 UTC

Fix with kmail 22.04.01.
