[xwiki-users] Exception during PDF generation: Property id previously used

Hi guys, Looks like I've run into a zombie bug: having two similar headings on pages included into one page gives exception when exporting to PDF. I've checked JIRA and there it is marked fixed in 1.4: http://jira.xwiki.org/browse/XWIKI-2124. Can anyone confirm a zombie bug or hint me what I might be doing wrong? Thanks, Andrey
