Unfortunately fix of BLOG-217 (commit a98bbd5) has an error in line 292 of file RssCode.xml.

The line reads: " <title>$escapetool.xml($entryDoc.getValue('title')</title>"

Correct would be: " <title>$escapetool.xml($entryDoc.getValue('title'))</title>"

So please fix by adding a closing bracket after 'title'!
