RSS feed doesn't filter personal labels

I'm still seeing CONF-8864 in the Confluence trunk, despite it being fixed in 2.5.5 and the "testFeedDoesNotContainPersonalLabels" test passing.

Original description follows

The labels field in RSS feeds doesn't properly filter out personal labels (i.e. my:favourite)

e.g.

<entry>
<title>Atlassian Delicious Feed (updated)</title>
<link rel="alternate" href="http://extranet.atlassian.com/display/DEV/Atlassian+Delicious+Feed" />
<category term="atlassian-culture" />
<category term="favourite" />
<category term="delicious" />
<category term="rss" />
<category term="favourite" />
<category term="favourite" />
