Bug#850999: seaborn: FTBFS: Test failures

[Ole Streicher]

Hi Andreas,

just a few comments -- I will not have time at the weekend to fix it myself.

The problems seem simple: First, buth RC bugs could be merged IMO since
they point to the same problem. The two arrays are only "nearly
identical"; unclear why, but I would just change the equal to a
"almost-equal" and report this upstream.

#849368 documents another failure as well; IMO the according test could
be extended to compare either with "blue", or with the 4-tuple. The
latter seems to be returned by matplotlib 2 (where the get_axis_bg() is
deprecated anyway).

IMO both changes could be done quickly, but my sun celebrates 3rd
birthday tomorrow, that is more important :-)

Cheers

Ole

Hi,

During a rebuild of all packages in sid, your package failed to build on
amd64.

Relevant part (hopefully):

Amazon Web Services, using a clean, minimal and up-to-date chroot. Every
failed build was retried once to eliminate random failures.
