it's a very old problem . i chose by default to not render html received messages for almost all messages html rendering is not executed and kmail supplies a link "ici" (here) at the top of the message to activate the html rendering . for some messages html rendering is not executed and kmail does not supply a link "ici" (here) at the top of the message to activate the html rendering i must ask for displaying the frame of the message then clickong on the line "html document" to have the link "ici" to activate the html rendering Reproducible: Always
Created attachment 86607 [details] there is no link "ici" (here) to activate html rendering
Created attachment 86608 [details] frame of the message i must ask for displaying the frame of the message then i must click 2 times on the line "document html" accordding to have the link "ici"
Created attachment 86609 [details] the message with the link "ici" (here)
Created attachment 86610 [details] the message
You have a mail with html + text version so it will render text by default you doesn't want html. So it's not a problem and it's good as mail
so i close this bug
