[xwiki-users] Exception while patching

Hi all, I've recently updated a couple of XWiki installations to 1.2.6932. Either with old documents or with new ones, when I try to see a given revision of a page, any of them, I get the following exception: Error number 3103 in 3: Exception while reading document version {1} Wrapped Exception: Error number 13027 in 13: Exception while patching Wrapped Exception: line::java.lang.NumberFormatException com.xpn.xwiki.XWikiException: Error number 3103 in 3: Exception while reading document version {1} Wrapped Exception: Error number 13027 in 13: Exception while patching Wrapped Exception: line::java.lang.NumberFormatException at com.xpn.xwiki.doc.XWikiDocumentArchive.loadDocument(XWikiDocumentArchive.java:319) at com.xpn.xwiki.store.XWikiHibernateVersioningStore.loadXWikiDoc(XWikiHibernateVersioningStore.java:162) at com.xpn.xwiki.XWiki.getDocument(XWiki.java:1060) at com.xpn.xwiki.web.XWikiAction.handleRevision(XWikiAction.java:257) at com.xpn.xwiki.web.ViewrevAction.render(ViewrevAction.java:29) at com.xpn.xwiki.web.XWikiAction.execute(XWikiAction.java:148) at org.apache.struts.action.RequestProcessor.processActionPerform(RequestProcessor.java:431) at org.apache.struts.action.RequestProcessor.process(RequestProcessor.java:236) at org.apache.struts.action.ActionServlet.process(ActionServlet.java:1196) at org.apache.struts.action.ActionServlet.doGet(ActionServlet.java:414) at javax.servlet.http.HttpServlet.service(HttpServlet.java:690) at javax.servlet.http.HttpServlet.service(HttpServlet.java:803) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:290) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at com.xpn.xwiki.web.SetCharacterEncodingFilter.doFilter(SetCharacterEncodingFilter.java:117) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:235) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:206) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:228) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:175) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:128) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:104) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:109) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:216) at org.apache.coyote.http11.Http11Processor.process(Http11Processor.java:844) at org.apache.coyote.http11.Http11Protocol$Http11ConnectionHandler.process(Http11Protocol.java:634) at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:445) at java.lang.Thread.run(Unknown Source) This happens both in wikis where I've imported the 1.2 .xar and where I don't. Comparisons between releases usually show the whole content highlighted green. Or no changes at all. New documents work fine for "a while". I say "a while" because I am not able to identify the point where they start behaving as the old ones. Please, could you help me with this issue! Thank you so much.
