Hmm, I had such a problem once with both Mozilla and Thunderbird, but you 
said you've purged the local copy. BTW: There are two files per mailbox, a 
*.msf and one without extension, you need to delete both, the msf is the 
index, but also stores the settings, like download status.

The problem was that the user had more than 2GB mail in INBOX, what let 
the local storage (mbox) of both applications crash silently. When 
restarted the complete file was mixed up, some mails OK, some headers 
only, some header and body mixed up.
This can happen anytime, I've noted, when the sync process is interrupted 
very heavily, e.g. when you terminate mozilla during sync. I later tested 
this with a smaller mailbox as well.

The solution was:

a) move some mails to lower the INBOX below 2GB manually in the Maildir, 
and
b) remove the INBOX cache on the client.

Bye.
