3) What is expected to happen via the Terminal:

cd ~/Desktop && wget https://bugs.launchpad.net/ubuntu/+source/openoffice.org/+bug/482330/+attachment/1028200/+files/test.ods && unoconv --listener && unoconv -f xls test.ods

is the file is converted quickly and successfully.

4) What happens instead is it hung without creating the new document. I clicked Applications -> Office -> LibreOffice Calc and then it crash.
