Description James Pirie 2018-05-31 11:12:25 UTC 
Application: kontact (5.7.3)
 (Compiled from sources)
Qt Version: 5.9.5
Frameworks Version: 5.44.0
Operating System: Linux 4.15.0-23-generic x86_64
Distribution: Ubuntu 18.04 LTS

-- Information about the crash:
- What I was doing when the application crashed:
Writing a mail to someone which was saved in the outbox "local folders" which I do not normally use however I have been having general difficulty with KMail and was expermenting.
The mail initially did not send because it was using an incorrectly set up smtp account.  I corrected the error in the send account and then the program crashes every time I click on the mail in the outbox

The crash can be reproduced every time.

-- Backtrace:
Application: Kontact (kontact), signal: Segmentation fault
Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1".

Same issue as in bug 398570.

Please state where the 'libKF5MessageViewer.so.5abi4' library comes from. If unsure, ask for help in a forum of your distribution.

Sorry Christoph, I did not get notified of your request above.  Today I received a notification that this message had been waiting for information for 15 days!  Odd that I receive the nag but not the original question.
The good news is that this situation has resolved itself with no input from me.  I can only assume an update to some component or other has provided the solution?  IN any case, KMail now operates as expected and this bug, I guess, can be marked as "resolved" or do we mark it as fixed but no resolution somehow?

My knowledge level would have made answering your question tricky but, as you suggested, I would have asked in Kubuntu forums and done my best to get the correct information.  If you would still like me to do this then please say so and I will endeavour to provide the info.

For the moment though, all is well with Kontact and Kmail on my machine.

Thanks for the update; changing status.
Comment 5 Sebastian Turzański 2024-01-08 15:17:32 UTC 
I confirm the bug still exists in latest kde 5.27.10 -> 5.24.4 (23.08.4)
Comment 6 Sebastian Turzański 2024-01-08 15:18:57 UTC 
this bug has been now confirmed on Opensuse Tumbleweed, lasting for about 6 months now
Comment 7 Sebastian Turzański 2024-02-15 09:01:32 UTC 
HI all
I was able to  narrow down the case

When sending a signed mail with default openPGP for an account all works fine if I send it instantly.
All works fine if I you send later but without openPGP signature

If I select send later the openPGP signed mail is put to OUTBOX and sits there .
When I try to open this message to see or modify it kmail or kontact crashes.
This bug has been bothering me for years but now I narrowed it down to the case where it only happens with SIGNED mails that are opened from outbox folder.

STEPS TO REPRODUCE
1. Create openPGP signed mail
2. Send it with "send later" option
3. Go to outbox and try to open this mail

OBSERVED RESULT
Kmail/Kontact crashes , when you run it again kmail opens it's main windows plus addtional windows with the signed outbox mail it failed to open before crash

EXPECTED RESULT
