When calculating in tables in writer these documents are destroyed when saving. After reopening the document and clicking inside a cell all table cells change to "** fehlerhafter Ausdruck **" ("error in expression" or so in english). The failure happens in the save process, because the saved file is already damaged. One (the first) equation is duplicated to all other table cell values. This behaviour occurs under Arch Linux x86_64 with libreoffice 3.3.0.4-x and openoffice 3.3.0-0, is repaired in openoffice 3.3.0-1
