I can reproduce the OP's error with Ubuntu's libreoffice version (3.5.2-2ubuntu1) on 64-Bit (another comment states that it is not reproducible on 32-Bit Xubuntu, though -- see the Ubuntu Bug Report: https://bugs.launchpad.net/ubuntu/+source/libreoffice/+bug/986205 ).
With Libreoffice from the TDF (i.e. installing all the .deb's in LibO_3.5.2rc2_Linux_x86-64_install-deb_en-US provided by http://www.libreoffice.org/download/) I can not reproduce it, so the problem seems to be Ubuntu (or Debian) specific.
