William just closed 2045 as a duplicate of 2038, which has the same
types of error messages.
Here are the error messages I get (2.10.1 on Ubuntu 7.10, Pentium 4):
sage: plot((1-x^2)^(0.5),(x,1,10))

TypeError: 'float' object is unsubscriptable
The above error was with the notebook.
An interesting but hopefully unrelated error is obtained from the
command line (see below). I originally built sage 2.10.1 (from source)
in the ~/download/sage-2.10.1/ directory, but subsequently moved it to
~/sage/ directory. However, the error below still seems to have some
things pointing to the download directory. Is there something I have to
do to safely move the sage directory after building?
sage: plot((1-x^2)^(0.5),(x,1,10))

Unfortunately, your original traceback can not be constructed.
Thanks,
