Alex,
    Why is that chicken & egg?

In theory, shouldn't you be able to put PloneCollectorNG 1.2.8 in your 
new Plone 2.1 products directory, then when you try to migrate to Plone 
2.1 it will have PloneCollectorNG 1.2.8?

If you're trying to migrate to Plone 2.1, with PloneCollectorNG 1.2.7 in 
the Products dir, then I wouldn't expect that to work..

Or maybe I misunderstood you here..........

If it proves hard to confirm that just from your log, had you thought of 
  simply on a test copy of your data, deleting PloneCollectorNG from 
products (+ probably need to delete any related content first, although 
with some luck migration should just ignore content from a 
no-longer-installed product), and try to migrate? If it then works (or 
breaks somewhere else  ;-(  ) at least you know PloneCollectorNG was the 
problem.

In such sticky migration situations, using a debugger really helps. You 
can patch stuff to make it work here because it only has to work once...
