I'm not necessarily convinced that the corrupted titles are causing the supplemental status however. Why would that happen? In our case any way, the affected pages still have unique titles: e.g. Widget Ratings on Exmaple.com GARBAGE CORRUPTED WORDS.
What makes you think that the corrupted titles cause supplemantal-ness?
And because when this same thing happened on my other sites, as soon as the corruption disappeared, the pages Came Back From Supplement City (I was suddenly reminded of a David Bowie song)
The thing is, the bit of text that it's taking off the page and adding to the page title is the navigational text - so it's the same on every page, and there's enough of it that I believe it's make the pages look like duplicate content.
