Hi guys, when trying to open Main.WebHome I get an error concerning invalid byte 2 in 4 byte UTF-8 sequence. --snip- com.thoughtworks.xstream.io.StreamException: : Invalid byte 2 of 4-byte UTF-8

open the same document before and am now unable to do so, without having changed anything in this particular document. Furtehrmore I do not use UTF-8 at any place. The MySQL database is in Latin1, and the settings in Tomcat and XWiki are all approritae to ISO-8859-15. Since this might be a bug or at least it feels like it to me, I thought, I post it here. Cheers, Sebastian
