I'm currently doing lenny->squeeze->wheezy upgrade tests to find
packages that "did something wrong (but did not fail)" in lenny or
lenny->squeeze that makes the upgrade to wheezy fail (or makes
removing/purging in wheezy or some other checks in wheezy fail).
Upgrading long grown systems should work without problems ...

Of course this uncovers installability issues in lenny or lenny->squeeze
upgrade issues. I don't expect most of these to get fixed in squeeze -
but they should be documented anyway. I'll also implement workarounds
(if possible) in piuparts for non-leaf packages.
So, in case you have a suggestion how to work around this ... let me know.

without checking any logs ...: piuparts has seen a lot of improvements
since then and that probably increased the test coverage of the archive
(including old releases)
or maybe the problem was already discovered by earlier tests, but nobody
had the time to analyze the failed logfiles and therefore no bugs were filed

PS: for wheezy I filed a few similar bugs w.r.t. octave3.2 removal that
were finally resolved by adding a few more Breaks (in lapack and related
packages, but not octave itself) to hint apt to use a better ordering of
the operations ... i.e. remove octave3.2 earlier
