Description orelie 2015-10-18 18:45:19 UTC
Kmail freezes the whole plasma system if all  following requirements are met at the same time:

1. activated spell checking before send
2. ctrl + return used to send the email
3. email contains spelling mistakes

If I click the "send" button everything will work
If I disable the "spell check before send" (don't know the correct translation) everything will work
If I don't have spelling mistakes everything will work
(Which is a description of: all the following requirements...)

It seems to be related to the spell checking mechanism since kmail freezes after I close the spell check window.
Manual spell checking works (same as "spell check before send" when clicking the button)

Removing the kmail2rc doesnt change anything.

Are there any logs? Journalctl doens't seem to contain relevant information.

Reproducible: Always

Comment 2 Stephan Diestelhorst 2016-03-29 19:08:28 UTC
I think I have a similar issue, I have checked "confirm before send" and am enforcing a spell check, too via "Check spelling before sending".

I have created a small video showing the state of affairs: https://www.youtube.com/watch?v=Bg_JF5FLhac

Kmail Version 5.0.2

Qt 5.4.2 (built against 5.4.2)

I'm having the same problem using kontact5-16.04.2. The problem apparently is that window focus is on the spell-checker window, while the "send email" dialog box appears above it with keyboard focus. I once managed to click the send button by keeping it pressed for a long time, but in general the session is frozen during this issue, Xorg and kwin consume lots of CPU time, and the input during the time the session is frozen is replayed after it is resumed.
Comment 4 Carlos Henrique Merces Moreira 2016-11-16 20:49:49 UTC
I confirm this bug is happening on KMail 5.3.3(KDE Frameworks 5.27.0, Qt 5.7.0, window system xcb), to reproduce this bug you need to activate the options "Check spelling before sending" and "confirm before send" as Stephan Diestelhorst said in [2].
