How to export from FreeMind 1.0 Beta 2 to LibreOffice?

So I tried to export a huge FreeMind mindmap to LibreOffice / OpenOffice.org Writer format and tried, as usual, in Freemind: “File -> Export -> To OpenOffice.org Writer format …”. But that failed, as it exported only the first level of nodes and nothing else.

This seems to be a bug in te FreeMind 1.0.0 Beta 2 version I was using; maybe the file export filters have not been adapted to the new file format introduced in version 1.0? After some messing around with HTML, MS Word exporting, LaTeX exporting and the clipboard, I finally found an elegant, functional workaround: open and export your mindmap with FreePlane to OpenOffice.org Writer format.

FreePlane actually is a nice FreeMind clone that can still read the FreeMind file format.Exporting works exactly as outlined above for FreeMind. I used FreePlane version 1.1.3 for the exporting task, which happens to be available in the Ubuntu 12.04 package repositories.
