Bug 30956 – intermittent parse errors with javascript showing through markup

javascript is visible

Given that I'm using Safari 4.0.3 (6531.9) on Snow Leopard (but not the Leopard version of 4.0.3) or the latest Windows Safari, or a Webkit nightly (e.g., 6531.9, r50235) on Snow Leopard (unknown if it happens on Leopard)
When I go to http://space.iremix.org/spackle1/units/ 
Then I should see a page that includes a YUI table that lets me sort.

However, if I click back and forth between Roles and Units and Projects, every dozen or two page views will result in an error state where javascript is poking through the markup (see screenshot). And the Safari error console reports a parse error. But View|Source appears correctly.

This problem does not occur with IE or Firefox. This does not appear to be a server problem (I've hit the same URL many times and diff'd the output to no avail).

I suspect this is some sort of cache corruption bug, but can't say for sure.

Help!

Thanks.

I do not believe this happens with nightlies on Leopard, but does with Snow Leopard.

This appears to be fixed in r51825. 

Whatever it was, it hasn't made it downstream into the Chromium builds yet.

Just to clarify that last update, I've not noticed this problem since using webkit nightlies since r51825, including the most recent.
