SUMMARY

kmail crashes when I click on a mail address in the body of an email. Unfortunately it seems, that some data gets corrupt during the crash and I am not able to start kmail again. I manually deleted some kmail / akonadi related files without success. But I could create a backup using PIM Data Exporter. After deleting everything I found in ~/.local/share and ~/.config/ and restored the backup, it worked again.

STEPS TO REPRODUCE
1. Open a mail with an email address in the message body
2. click on the email address

OBSERVED RESULT
kmail freezes / crashes. When I close it, it does not start again. Instead it is crashing with the message

EXPECTED RESULT
I want to write a new email to the address, I clicked on.

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Arch Linux
KDE Plasma Version: 5.24
KDE Frameworks Version: 5.90.0
Qt Version: 5.15.2

The original crash is described in Bug 449891. This bug is about the corrupt data.

Comment 2 Hauke 2022-02-11 10:13:46 UTC

Can confirm this bug (also using Arch with KMail 5.19.2). But for me answering any mails (not only mail with an mail-adress in the message body) causes this crash.

Removing all files in ~./local/share/kmail2/autosave/ solved the startup issue and KMail starts normally. Answering a mail results in a crash again.

After the crash this autosave folder contains one file with the following (anonymized) content:

To: ??? ??? <???@???.de>
Date: ???
Message-ID: <1962715.oMNUckLgyt@???>

The log output in the moment of the crash is the following:

*** KMail got signal 11 (Exiting)

/tmp/messageviewer_oqpWBI.index.2 was not removed .

This epoll_wait warning is printed a thousand times. The string "Ungültiger Dateideskriptor" is German for "Bad file descriptor".

Can confirm, that this bug is caused by answering any mail.

Can confirm that, too. Thanks for the "fix".

Seems a duplicate of https://bugs.kde.org/show_bug.cgi?id=449826
Issue is with gpgme 1.17.0.

Comment 5 Hauke 2022-02-13 10:42:52 UTC

Fixed for me with KMail 21.12.2-2 (more details here: https://bugs.kde.org/show_bug.cgi?id=449872#c11).

Comment 6 sedrubal 2022-02-13 13:18:30 UTC

Yes, the update also fixes it for me. Thanks.
