--- Comment #15 from Sandro Knauß  ---
There was an outstanding merge request since November, as I found the issue
from our CI infrastructure but never heard about this bug yet, because I
normally use Encrypt+Sign: 
https://invent.kde.org/pim/messagelib/-/merge_requests/14

Workaround is use Encrypt+Sign, as this is using a different code path, that
was not hit by this one.

Sign alone is not enough :-)
As you could reproduce it there is probably no need anymore to test the devel
version, correct?

I created a openpgp key and it crashs indeed when we encrypt.
Sign with same key works.

Changing to confirmed.

Sorry, but a *mayor feature* - encryption - is broken in KMail.

KMail is unuseable at the moment if you have to care about privacy.

Can you please fix this?

Thank you!

For what it's worth, I'm seeing exactly the same issue. Encrypting mails pops
up the key chooser, but when I finally choose OK on Encryption Key Approval
dialog the mail becomes lighter coloured as if it were completely locked and
then after a couple of seconds kmail crashes. I also see the same event loop
warning and no Konqi appearing.

This is the best bt I can deliver at the moment (given I have not checked what
debug packages I need)

If I understand you correctly, this is usual behavior for a gdb session. At the
moment, gdb chimes in, all debugged processes are halted.

Just type bt or bt -full and post the result.

Also, you may want to just run gdb kmail.

Thanks for the hint, Christoph. I was actually following
https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports#Retrieving_a_backtrace_when_an_uncaught_exception_is_causing_a_crash
which leads to a kontact window not being properly redrawn, means showing the
background of whatever was just on the screen.
So I cant use kontact to reproduce the crash.
Tried already to switch video driver from nvidia to intel, no change in
results.
Any idea?
