OK, I've found out some more stuff about the problem.  Of course, it
wasn't really random.  The culprit is a linked stylesheet.  Every time
I alter the sheet in some way, I get the SERVER_URL KeyError.

I can't really see why this should be happening, though.  The 
absolute_url() in question is in the main body of the document, not
the stylesheet.  

Is perhaps the acquisition wrapper not getting applied to the document
until after the linked objects are also downloaded, or something
strange like that?

I haven't the time time to pursue this right now, but I'll attempt to
make a simple, reproduceable example and submit it to the Tracker.
But just in case I get time to debug it, where might I start?  I'm not
very familiar with the Traversal / Publishing stuff.
