Tim,

is no handler for the exception you are throwing.  Off hand it does not seem
like a GDAL problem. 

If you have a concern about the GDAL (really PROJ) error message
being written to stderr, you can do the following to supress error output
to stderr:

  CPLPushErrorHandler( CPLQuietErrorHandler );
