Comment (by darij):
Here is the bug. First, let us doctest ncsf.py with this branch normally:
{{{

}}}
The failure was in a doctest which is **not** #long time!
There must be some coercion case poisoning going on, probably similar to
#15248, possibly connected to #10906. Any comments are welcome, since I
don't have enough time for Sage these days.
