Summary0001152: Bad output in neato for small edge lengths

I ran into a strange problem with neato. I used the attached dot file to generate a jpeg: if I keep
the statement forcing the size
          graph [overlap=scale,ratio=fill,size="6,6!"]
I get one ugly image; without it neato seems to loops infinitelly and keeps on grabbing memory
(my ram occupation increased by 1.5GB) and I get nothing ..
Any ideas? Bad graph specification? (other similar specifications worked fine ..). It is a 'view'
of a NYTimes jobs rss feed where distances are calculated as the cosine distance between
the titles of each feed item (and points correspond to items).
Additional Information

[erg] It appears some type of overflow is occurring, related to having
an edge with len=0.00001.
The final stress is more than the initial stress, and negative stress
is reported.

Even when overflow doesn't occur, as in a small graph, having a small
edge len induces an extremely large initial stress value. It's unclear
why this is happening.
