Description thomas 2022-02-09 08:33:29 UTC
SUMMARY
***
I am using S/MIME encrypted emails quite heavily, however after a OS reboot yesterday, Kmail would crash immediately at launch.
After some investigation it turned out that the mail Kmail tried to display during start was encrypted. After removing that email via AkonadiConsole Kmail starts again, but the moment I click on another encrypted email it will crash again.
***


STEPS TO REPRODUCE
1. Launch Kmail
2. Select S/MIME encrypted email in message list
3. Crash

OBSERVED RESULT
Crash

EXPECTED RESULT
Show the email content

ADDITIONAL INFORMATION
Starting kmail from within a terminal shows the below, the flite message is a red herring in my opinion, it's not installed and shows right after the start, not at the time of the crash. I did install flite to see what happens to the error, no effect other than that flite message disappearing, so removed again.  Things will be quiet until I select an encrypted message which immediately leads to the signal 11 message and a lengthy systemd-coredump in journalctl.

Comment 1 thomas 2022-02-09 13:59:21 UTC
Went through the Plasma 5.24 update this morning, unfortunately no luck.
Comment 2 lod 2022-02-09 14:35:35 UTC
I'm running in a similar problem. When I try to reply on certain mail accounts (just one of the two are encrypted)  kmail/kontact crashes and I have to remove the kmail2 folder from ~/.local/share to be able to start it again.

Application: KMail (kmail), signal: Segmentation fault

Comment 4 demm 2022-02-12 16:16:57 UTC
This is an issue with gpgme 1.17.0 only, downgrade to 1.16.0, and kmail runs just fine with encrypted mails.  But is this an issue for gpgme, or needs kmail adjusting for new gpgme?

Rebuilding messagelib fixes this. Looks like gpgme 1.17 had an unannounced ABI break.

Thank you very much for the quick turnaround! I can confirm things are working fine again with today's gpgme update.
