Martin, 

The last line in your log is:

odbc:SQLGetInfo: info option 84 not supported

InfoOption 84 is SQL_FILE_USAGE.  

I committed a patch, attached, to support this option; it now returns
SQL_FILE_NOT_SUPPORTED, which I believe is correct.  

I don't have an odbc driver installed and cannot compile the driver without
the appropriate header files.  Please tell us if it works for you.  

ODBC hackers: Our SQLGetInfo doesn't respond according to spec when an
unsupported option is requested.  The MDAC SDK documentation for it
describes very particular behavior.  That might be why OpenOffice crashes.  

Details:

SQLGetInfo supports the SQL_FILE_USAGE information type. The returned value
is a 16-bit integer that indicates how the driver directly treats files in a
data source: 

* SQL_FILE_NOT_SUPPORTED -- The driver is not a single-tier driver. 
* SQL_FILE_TABLE -- A single-tier driver treats files in a data source as
tables. 
* SQL_FILE_QUALIFIER -- A single-tier driver treats files in a data source
as a qualifier.
