[pygtk] addtion to gnomevfs.async.get_file_info()

[Ogz]

For may previous mesage here is an addition:

 File "./sefir.py", line 39, in fileinfo_callback
    print info.size
ValueError: size field has no valid value

I am tryiing to get the size of a file from a remote machine.

I tried to use the same approach at the gnome-python10.0
examples/async.py. But i seems i miss something.
