[Bug 6329] New: Unchanged page reporting valid and invalid at different times

I've noticed that some pages are reporting valid at one point in time and
invalid later despite nothing in the page having changed.

This occurs with 3 or 4 pages I'm testing, all of which are presumably invalid
with a common error (no space before a class=). I've reduced this down to a
test case which reproduces the bug I'm seeing
(http://deeden.co.uk/misc/quantum.html). There is no space before class="hello"
on line 10 and this is what the validator reports on when it views the page as

As I write this the page is being reported as invalid, however in a while
(whether  minutes or hours) it will report it as valid. If I retry the page a
few times it will continue to say it is valid until it eventually starts
reporting it as invalid, again consistently.

I've checked that the headers being sent for the page are the same during both
valid and invalid periods and they are, so it's not something to do with that.

The behaviour I see is happening both through the web interface and the
WebService::Validator::HTML::W3C perl module.
