KMail crashes when I open certain e-mails. This has started today, after I upgraded my KDE Apps to version 23.04 and KDE Frameworks to 5.105. I haven't been able to figure out what those mails have in common, although most of them seem to be forwards, possibly with attached images.

The same e-mails are viewed perfectly in another computer with KMail 5.22.3.

This is the backtrace (identical in all the e-mails that produce the crash):
