Hi Kenny,
this more or less fits what I said last time but doesn't shed much new light.  
Out of curiosity, what happens if you take an Annotation object a1 from 
resource1 and use it as a key to your SQLGraph, e.g. something like this:

a1 = resource1['key you know is in the mapping']
for a2, e in graph[a1].items():
   print a2, e

They should be pairs of Annotation objects from resource2, and row objects from 
edges. 

I'd also like to see what you get when you iterate over your SQLGraph, e.g.

for a in graph:
   print a
   break # quit after 1st value

Its iteration values should be Annotation objects from resource1.

I just want to be sure that your SQLGraph is working by itself, before 
considering the interaction with graph query.

A few points:

- are you really still working with 0.8.0-beta1?  That was just a beta.  We've 
fixed a lot of bugs since then.  I strongly advise you to get the latest 
release.

- at the point where it crashed, it expected an (Annotation) object but instead 
got a long.  That is suggestive -- long is the data type that MySQLdb uses to 
return integer values, so this presumably came from SQLGraph.
