I'm thinking that there must be some sort of conflict between the GEOS
and geodjango. Has the API changed significantly lately?
After installing the latest SVN release (3.4.0dev-CAPI-1.8.0), things
got worse, not better. Now no geometry will buffer, even super simple
example geometries from
1.12, and can confirm that both isValid and buffer
work correctly. The buffer operation does take quite a while and requires a
significant amount of memory.
So the geometry is fine. There may be some issues with GEOS.

Thank you Mr. Davis for your attention,
I tried your suggestion of buffering elements individually then
merging the buffers. I buffered several
