There are always going to be people who prefer to start fresh with a 
clean install of every version, and some of them are going to recommend 
it to others, often without explaining why they prefer it.  The same 
goes for just about any method that can be used to go from one version 
to the next.  Have you ever considered asking these people why the don't 
like using the official upgrade path?  I know that I certainly would 
before taking their advice, and I'd think long and carefully about their 
reasons, because I understand that what works right for them may be 
exactly the wrong thing for me if my circumstances don't match theirs.

Have you checked Bugzilla to see if there are any reported bugs with 
effects similar to yours?  If there aren't, have you considered 
reporting this?  If you haven't checked, why not?  (This isn't a 
challenge, BTW, but a serious question; you may have good reasons not to 
be doing this, and if so, I might learn something from them.)
