In KMail Versiom 5.5.0 it is still working as you are describing accept viewing
source is not very fast, but my machine may be slower than yours, also in the
1.2 MiB email size some are readable in the normal way, others are not, and a
9.5 MiB email took 3 minutes 44 seconds to view source, and like most large
emails, never show in the preview pane. Also view source consumes 100% of one
CPU until the view source loads.
