Fixed in 59e556e - a tag is needed, but sage.libs.pari is a better choice.

OK. I thought the tag is completely out of sight. But it is in TESTS block, and hence not visible anyway.

This goes through Polynomial.root, which tries to invoke numpy for low-precision float fields. (It could fall back to using PARI, but this would require a bit of refactoring)
