Thanks for the reply. It is that very "f.is_valid()" line that causes
the error, as indicated by the stack trace. (The next line is an
HttpResponse("foo").)
Is the above stack trace expected? The is_valid method appears cause
save() to be called. Is the issue (1) that save() isn't supposed to
throw a ValueError, or (2) that save() should not be called in the
first place?
