The problems:

This is caused by you having some optional Cremona database installed
and it is #5346 which has a trivial fix suggested by John - someone
just has to put a patch up and unless someone beats me to it I will do
it tonight :)
The other two failures are upgrade specific and happen when when left
over pyc and so files are around due to the Quaternion classes being
moved. One brutal fix is to do delete devel/sage* and to do a -ba.
The more fine tuned fix is to delete some py files and touch a couple
others followed by a -b, but I would need to look up the details.
