Subject and verb must match in number.
I see this error all the time, and it's really getting out of hand.
The other day, I was watching some show on the Discovery Wings channel about some newfangled helicopter. The narrator -- who, embarrassingly, spoke with a refined British accent -- said, "The first of five prototypes are scheduled to fly next year..."
(If you don't understand why that's an error, please email me.)
Consider, for example, this sentence I just ran into:
That's a syntactically valid sentence. But God help us, it's also gibberish -- and it's gibberish in a way that a mere proofreader could never untangle. If I were designing word processors that delivered electric shocks to the user, I would rather crank up the voltage for sentences like the above, rather than for people who use "are" with a verbose (but notionally singular) subject."By returning the file name at the end of the method, conversion of this file to other formats would be facilitated as well as testing that the postscript operation was actually performed."
Semantics

The problem you illustrated is purely one of semantics. That's a whole nother (:-) level, which I am going to avoid. Clearly, for the purposes of communication, one should tolerate some degree of bad syntax if that's the price for semantic clarity.
