thank you very much, lionel, but fortunately that problem had been already
fixed before nc6-0.3. you should probably consider upgrading to nc6-0.4, but
i don't know if there is already a debian package for the new version of nc6.

however, if you would like to help us with the development of nc6 and/or
other packages, we would be very happy. think about it and let me know ;-)
