If this happens repeatedly and it's just a spam mailbox, could you  
put the whole mailbox and the index files into a tarball and send it  
to me (or post a link or whatever, I think I can accept max. 10MB  
mails)?

The problem is that Dovecot has stored a cached MIME structure into  
dovecot.index.cache file, but now when it's trying to use it again,  
mail's contents have either changed or something else weird has  
happened. I think I had added several sanity checks to this already,  
so this assert shouldn't really have happened. But the same problem  
has existed for years, so this is getting a bit annoying problem.

Could it be possible that the mail's body had changed?

Anyway if you delete dovecot.index.cache file it should work again.
