[Cooker] Change in format of msec Diff and Security Checks?

[AAW]

Until today, msec's daily Diff Check and Security Check email came through as 
normal text emails. This morning's reports are attachments, unspecified 
binary data, base64 encoding.  I'm using kmail 
(kdepim-kmail-3.5.9-11mdv2009.0) under a kde3 session. I don't see anything 
in list of rpms installed in the last 48 hours that might be responsible. 
msec was upgraded several day ago. Or could it be file associations and 
related to the kde3-4 transition?

Thanks,
Arn
