When I run `sage -python` and then try to import something "specific"
(e.g. from the `rings` module), I get the following:
{{{

}}}
This also happens for other modules, e.g. `from sage.modules.all import
*`. However, it does not occur when I do
{{{
from sage.all import *
}}}
first. Likewise, the import works in ordinary `sage`:
{{{
$ sage

sage: from sage.rings.integer_ring import *
sage:
}}}
Issuing `sage -sh` before `sage -python` does not help though.
I'm running Sage 5.0 on Mac OS X 10.5.8.
