Hi,

I have such problem.

In my kmail settings I have:
[Setting] >> [Configure KMail] >> [Security] >> {reading tab}
Ticked >> PreferHTML to plain text
Ticked >> Allow messages to load external references from the internet
^^ However, after reboot, all the email I have as plain text, so I have go back to the setting, untick that 2 above, apply, tick them again, apply, and the everything is fine. After another reboot of the computer, I have to do this again, what is very annoying.

Is this a bug, or some problem with old cache configuration, as use kmail different version on the same laptop for the last 2 years.
