Actually, it is kind of interesting that this bug is being exercised at
all.  "client" is not a string in lib/python/Products/ZSQL/*.py,
lib/python/Products/ZSQL/*/*, lib/python/Shared/DC/ZRDB/*.py, or
lib/python/Shared/DC/*/*.  So, where is it being defined?

On the other hand, if you define a dtml method that has only contents
<dtml-var client>, a name space violation is raised, suggesting that it
is not a part of normal acquisition.
