Bug#918079: pandas: FTBFS: B-D on python-nbsphinx which is no longer installable nor built any more

[Thorsten Glaser]

Source: pandas
Version: 0.23.3-1
Severity: serious

See #917418 for “python-nbsphinx (0.4.1+ds-1) is not installable”.

src:nbsphinx (0.4.1+ds-3) now only builds the py3k package.

python-nbsphinx (= 0.3.5+ds-1) is installable and usable, but no
longer in Debian, so please move to python3-nbsphinx instead.
