Comment (by leif):
So far I only tested the files that previously failed for me (with the new
spkg and the Sage library patch applied).
I get the same `list()` errors (although prepended by some debug output it
seems, before the doctest error is printed), and sporadically the
`f.factor()` error -- with '''varying''' results:

(For me it's line 3910; presumably due to some other patch. The first
variant seems to occur more often. All tests run sequentially, FWIW.)
P.S.: Run 100 times from the shell, the test failed 51 times.
