"addColumn" tries to add default values for all catalogued objects
for the new column. This is a long operation when your catalog
is large. Long operations are prone to "ConflictError"s.
Install this product only, where there is no other "catalog" activity
(modifications, to be precise).
Usually, an isolated "ConflictError" is not problem. The
request should simply be retried.
However, some products are stupid about catching exceptions.
More precisely, they catch "ConflictError", too. This
prevents the automatic retrial.
The second exception ("not registered") is almost surely more interesting...
Do you get a traceback?
