I've seen it. They'd have to rewrite the abstract, state an actual result, prove it and rewrite everything in between. The "paper" is just grammatically correct but non-sensical glibberish from start to end.
If a referee accepts this paper conditionally, he might as well accept a blank page on condition that the author will put something there.
Well, if they rewrote the abstract, and proved their results, it would have meaningful content..
