New question #141393 on Graphite:
https://answers.launchpad.net/graphite/+question/141393

Hi!  I have been attempting to import collectd RRDs (as well as RRDs from other tools) into Graphite via both copying and symlinking.  

The UI notices that the files are in place, but renders an empty folder for their icon.  With a little investigation, I noticed that the HTTP calls for those icons were returning 500's like so:
**************************************************
KeyError at /metrics/find/
'ds'

Exception Type:	KeyError
Exception Value:	
'ds'

The relevant line of code is line #265 in storage.py:

    fh.close()

  def getDataSources(self):
    try:
      info = rrdtool.info(self.fs_path)
      return [RRDDataSource(self, source) for source in info['ds']] ...
    except:
      raise
      return []
class RRDDataSource(Leaf):

I did a little research on the web, and this looks quite similar to this discussion about changes to the python rrd bindings back in 2009:

Do you all have any insight into this issue?
