I was able to reproduce it with web2py
Version 2.4.2-stable+timestamp.2013.03.09.00.16.49
I attach a small sample that demonstrate the issue.
Just drop the attachment in controllers in an empty
application. it does not need any view and db connection
and table definition is in it.

The problem is with SQLFORM.grid.
I track it down to:
- sqlhtml.py (1817) in def url
`- sqlhtml.py (1824) when calling URL(**b)
`- html.py (357) when calling urllib.urlencode(list_vars)
list_vars contains the FieldStorage. So I guess the content of the upload
is used in urlencode.
The call to url() is the culprit and it's called in two places in sqlhtml.py:
line 1835:
referrer = session.get('_web2py_grid_referrer_' + formname, url()
line 1850:
def gridbutton(buttonclass='buttonadd', buttontext=T('Add'),
buttonurl=url(args=[]), callback=None,
delete=None, trap=True)
