Broken link for RSS icon in xwiki/bin/view/XWiki/WatchListManager

When Xwiki is passed through Apache proxy, it corrects links in its manner, and RSS feed icon link is corrected wrongly due to insufficient quotes.

Velocity code for xwiki/bin/view/XWiki/WatchListManager page instead of:
...
<a target="_blank" href="$profileDoc.getURL("view", "xpage=watchlistrss")" style="padding-left:16px;background:url($xwiki.getSkinFile("icons/black-rss-mini2.png")) left no-repeat;font-weight:bold;">$msg.get("watchlist.staytuned.rss.info")</a><br/>
...
should be:
...
<a target="_blank" href="$profileDoc.getURL("view", "xpage=watchlistrss")" style="padding-left:16px;background:url('$xwiki.getSkinFile("icons/black-rss-mini2.png")') left no-repeat;font-weight:bold;">$msg.get("watchlist.staytuned.rss.info")</a><br/>
...
Note simple quotes around '$xwiki.getSkinFile("icons/black-rss-mini2.png")' for url attribute.
