Bad, bad boy. Bad, bad, bad, bad, bad, bad... You get the idea :)

I'm not sure that this is the cause of your problems, but I wouldn't be
surprised. Other than that, I've *never* seen this error. If you can put
together a small test case (NOT Plone) that demonstrates this weird
error (could be a product with some failing imports, perhaps), I'd be
happy to take a look at it.
