I'm getting different error ("TypeError: calling <function
_singleton_method.<locals>.wrapper at 0x7f1039fca158> returned 100.0,
not a test") but indeed it FTBFS. To reproduce it, invoke debuild again,
after the first failure. Works all the time for me.

pybuild doesn't remove these files, here's what fixed it for me:
$ cat debian/clean
.coverage
coverage/*.so
