Description Simon Brown 2025-08-20 14:55:22 UTC 
Application: akonadi_maildispatcher_agent (6.5.0 (25.08.0))

ApplicationNotResponding [ANR]: false
Qt Version: 6.9.1
Frameworks Version: 6.17.0
Operating System: Linux 6.14.0-28-generic x86_64
Windowing System: Wayland
Distribution: KDE neon User Edition
DrKonqi: 6.4.4 [CoredumpBackend]

-- Information about the crash:
On composing a mail with Kmail I sent it usng the Ctrl+Enter short cut. After completing message signature I was notified that the dispatcher had crashed.

I have sent other emails today without problem. The only change for this one is that I noticed the wrong Identity was set. I removed the wrong identity in the settings and set it as default. As the compose dialogue had been open during this time I suspect it was trying to send with the deleted identity.

The reporter is unsure if this crash is reproducible.

Comment 1 Simon Brown 2025-08-21 08:47:34 UTC 
I think this problem was caused by an empty password in the smtp config. I had updated neon during the update to 25.08 so I think I had a partial upgrade. This seemed to cause wallet problems, which lead to recreating accounts. Another round of updates a day later and re-entering the passwords seems to have stopped the crash.
Comment 2 Ingo Klöcker 2025-08-22 20:10:32 UTC 
The crash isn't fixed (yet). It happens whenever the agent tries to ask for the SMTP password.

It will be fixed by https://invent.kde.org/pim/kdepim-runtime/-/merge_requests/264
Comment 3 Ingo Klöcker 2025-08-23 13:38:44 UTC 
The fix has also been backported for the 25.08 release series: https://invent.kde.org/pim/kdepim-runtime/-/merge_requests/265

Mail dispatcher agent needs widgets

The agent might have to ask for the SMTP password and this dialog is
a QWidget.
