Ok, then a runtime error, or at very least a warning 
is warranted. Because that means the properties namespace is
already polluted from an ant point of view, with an 
incompatible object. Since the basedir is the origin
from which all operations are performed, but it can't be
determined, the configuration should for sure considered broken.

How comes _this_ makes a difference, all of a sudden?!
Does a leading slash change the rules you mentioned 
above? 

The distinction between "location" and string values isn't
convincing anyway, since all OSes used today use strings to
designate files and directories.
