load uses "strip" on non-strings

[williamstein]

I got this bug/traceback today by making a file grader.py and a file grader.sage (their content doesn't matter).

sage: import grader
sage: load grader.sage
---------------------------------------------------------------------------
AttributeError                            Traceback (most recent call last)

/Users/wstein/edu/2010/480/grading/<ipython console> in <module>()

/Users/wstein/sage/build/sage/local/lib/python2.6/site-packages/sage/misc/preparser.pyc in load(filename, globals, attach)
   1487             return
   1488         
-> 1489     filename = filename.strip()
   1490     
   1491     if filename.lower().startswith('http://'):

AttributeError: 'module' object has no attribute 'strip'
sage: 

The above bug is the fault of the rewrite I did of load and attach, so is my fault.

Did I miss something?

If I create both files foo.py and foo.sage, then

sage: import foo
I am foo.py
sage: load foo.sage
I am foo.sage

doesn't give an error (in 4.3.5).

I'm using 4.3.4 and I see the same thing as leif -- worksforme. Perhaps the content of grader.py and grader.sage does matter?

Changed keywords from none to sd40.5

This still works properly on 5.1.beta0. In two years no one has reported or reproduced this bug; I propose we close it.
