KMail crashes

SOFTWARE/OS VERSIONS
Linux/KDE Plasma: Ubuntu 22.04
KDE Plasma Version: 5.23.3
KDE Frameworks Version: 5.88.0
Qt Version: 5.15.2

ADDITIONAL INFORMATION
It is a HTML email that contains an embedded image. I decoded the base64
content myself, removed the image and re-encoded it, and it didn't crash
anymore, so I guess the image may cause the problem. The email is OK with
Thunderbird.
(It is a batch-sent mail, and shouldn't contain any personal information. The
content is to warn that do not click any suspicious links.)
