characters entered as document title must be escaped or a cascade of bugs occur

Lets say I create a new document http://nielsmayer.com/xwiki/bin/edit/Timeline/foobar

• for Title, enter "this title has "quoted" words in it"
• click "save and view"
• the breadcrumbs show correct: "Timeline: this title has "quoted" words in it" ; it also displays correct in browser title-bar.
• Click "Edit" on that document ( http://nielsmayer.com/xwiki/bin/edit/Timeline/foobar )
• Note the title is now "this title has " : the part after first entered '"' is truncated
• Note that other scipts that use the title now fail, e.g. http://nielsmayer.com/xwiki/bin/view/Timeline/TL1?action=xml&xpage=rdf (XML Parsing Error: not well-formed)
• Removing the '"' character from the title fixes the failing scripts, and the title is preserved between saves and views.

I was unable to use any combination of "e; %22 or other means by which i thought i could escape a quote that needed to be in a title.

Note that using those replacements worked, they just didn't display quotes, just the original codes. Backquoting was ignored...
