Looks like a limitation in the conversion from Row.at() into ColData, which
takes only a char* in the constructor.
I don't know if Warren has fixed this in his private/devel tree or not.
This sounds familiar to me and I don't know why. :-)
Might take me a while before I can write a patch for this, given
time constraints. Should be easy to do, if someone wants to tackle it.
Look at Row::at(), the ColData template, and the const_string used in the
ColData typedef. Then add an operator const std::string&() to ColData.
