I will not have much time in the next ten days (too many work commitments) to take care of this bug report: http://bugs.debian.org/341676 At any rate, the octaviz package is badly outdated and still contains the file /usr/lib/octave-2.1.71/liboctaviz.so. It would be good to get rid of this versioned directory, but I do not have time to investigate this. Volunteers are welcome. -- Rafael
