Fixed in this changeset (http://hg.savannah.gnu.org/hgweb/octave/rev/80b9a9e1c965). The change was on the development branch so you will need to build from Mercurial sources or wait for the next stable release to see the fix.

According to matlab's help for roots, leading zeros in the vector of poly coefficients are discarded before computing the roots.
