LoadFromFile should convert %20 to space in URLs

[GoogleCodeExporter]

From Hans van Eijsden:

When I enable ModPagespeedLoadFromFile, I get a lot of errors in my Apache 
error log.

My config rule: ModPagespeedLoadFromFile "http://www.weblogzwolle.nl/images/" 
"/home/weblogzwolle/www/images/"

I discovered, that the problematic URL's are the URL's with spaces in them or 
%20's. Although they exist for Apache and the browsers, they don't, of course, 
seem to exist for the file system.
Is there a way, to let mod_pagespeed rewrite %20's back to spaces, when reading 
directly from the file system via ModPagespeedLoadFromFile?
Unfortunately, I had to disable ModPagespeedLoadFromFile completely for now.

Thanks!

Here is a part of my Apache error log:
