Error behaviour

[ZiNgA BuRgA]

Can't seem to reproduce at the moment, although I haven't done extensive testing.
I can't see how from the code either.  The break statement breaks from the inner-loop, not the outer loop which goes over the thread fields.  The break ensures that you don't get more than one error for each thread field, but you certainly can have more than one error amongst all thread fields.

Do you have a test case to reproduce the bug?
