Adding segment to VisitorInterest.getNumberOfVisitsPerVisitDuration causes SQL constraint violation

[ghost]

In 1.6, adding the "segment" query parameter like this:

<div id="widgetIframe"><iframe width="100%" height="350" src="http://example.com/piwik/index.php?module=Widgetize&amp;action=iframe&amp;moduleToWidgetize=VisitorInterest&amp;actionToWidgetize=getNumberOfVisitsPerVisitDuration&amp;idSite=9&amp;period=day&amp;date=yesterday&amp;disableLink=1&amp;widget=1&amp;segment=pageTitle!=nexus" scrolling="no" frameborder="0" marginheight="0" marginwidth="0"></iframe></div>

produces this error message:

SQLSTATE[23000]: Integrity constraint violation: 1052 Column 'server_time' in field list is ambiguous
