You didn't have a bright-white, flaky, crumbly floating layer on top of the beer by any chance?
Something looking rather like post #1 on this thread:

This pic looks very like something that I used to regularly get many years ago, and it gave a very solvent/antiseptic taste to the infected brews. In the quoted post, the micro-organism causing it produced no off-flavours - but whatever I had infecting my beer tasted very strongly and totally ruined the beer.
