This is indeed *very* strange. I have never used the OFX import in detail,
though; I only use the HBCI transaction import and these are always quite
simple. (No account creation involved etc.)

In OFX every element has an <UNIQUEID>. This character sequence is stored in
gnucash's accounts and/or imported transactions in their "kvp" structure
under "ofx" or "online_id", or "ofx/associated-income-account".
If you gunzip your gnucash data file and open it in a text editor, you will
find that each account and transaction has some XML elements under <slot>;
this kvp (key-value-pair) slots are our mechanism to dynamically add data to
almost any gnucash object. In this case, the kvp is used to store the
UNIQUEID from the ofx import.
Concerning that the matching accounts cannot be changed later: That has been a
RFE for a long time now, http://bugzilla.gnome.org/show_bug.cgi?id=98963 but
it still isn't there. Sorry for that.
Currently you can either edit your gnucash data file and remove the slot
values (simply replace the <value>...</value> part by <value></value>), or
alternatively you could modify the UNIQUEID fields in your OFX file so that
the next import will not see a matching UNIQUEID again.

That's fine; I just wanted to make sure you don't accidentally work with very
old code. In my case, I run a "svn update" daily before I start to work. But
your concerned part of the gnucash code isn't under active development by
anyone else anyway, so it probably doesn't matter whether you updated daily
or only after a few days. Note that if you supply a patch (use "svn diff"),
you should give us the revision number of SVN that the patch was created
against (see "svn info").
All the best,
