Hi Hugh, please find trace files attached. First one is for pyodbc used with virtodbc32_r.so, second is for pyodbc with virtodbc32u_r.so.
The mxODBC driver seems to work okay with virtodbc32u_r.so, but it has problems working under python 2.5, so I'd like to see if pyodbc can be used with unicode version of virtuoso driver.
