[Debian-science-sagemath] Help needed to backport ipywidgets blocking sagemath backport (Was: ... (Was: Backporting sagemath))

[Andreas Tille]

Hi again,

the versioned Build-Dependency fonts-font-awesome_4.7.0~dfsg-1~bpo8+1
was just accepted in Jessie-Backports.  It would be great if somebody
could have a look to solve the suspected infinite loop issue when trying
to build ipywidgets.

Kind regards

       Andreas.
