Dear Galaxy-Dev,

Last week I downloaded a fresh version of Galaxy with all stable updates. I've just come across a NameError in the upload.py tool. 

----
Traceback (most recent call last):
  File "/home/rob/galaxy-dist/tools/data_source/upload.py", line 390, in <module>
    __main__()
  File "/home/rob/galaxy-dist/tools/data_source/upload.py", line 368, in __main__
    dataset = from_json_string( line )
NameError: global name 'from_json_string' is not defined
----

A quick investigation led me to:
 from galaxy.util.json import *
 
and from there to json.py. I compared this file with my previous version and note that there are quite a few changes. 

The problem seems to be that from_json_string() is not included in the __all__ list of public functions... can someone tell me if this is a bug/oversight or if I'm missing something?

Cheers,

Rob
