KDE 4.1.3 using Kontact 1.3, KMail 1.10.3
Kubuntu Intrepid, fully patched

This happens daily for me from my Yahoo account.   Kmail presents the email body with blank subject, from, to, date, receiver, etc.   Inspecting the headers that /are/ presented in the email body, I see all begin with

; from=...

Recreating the index does nothing.

Here is an example of the body:
