[galaxy-dev] checkers

Hi, I recently update to the latest dist release and I'm getting this error whenever I try to upload files Traceback (most recent call last): File "/storage/home/galaxy/test/galaxy-dist/tools/data_source/upload.py", line 11, in from galaxy.datatypes.checkers import * ImportError: No module named checkers Should this module be provide with Galaxy or do I have to download it from somewhere?
