document with free connectors
PowerPoint 2013 does not use primitive lines but straight connectors. When it exports to .odp format, it writes a draw:connector element with a draw:transformation attribute, which holds the rotation of the line. When you open that file, the connector is drawn, but not rotated.
In the attached document the connectors should meet with their left point in the middle of the cross.
This one is fixed (see bug report at AOO: https://issues.apache.org/ooo/show_bug.cgi?id=121965 )
