UseExceptions masking proj4 errors

Description

While testing a script on a machine where python-gdal had been manually installed, several errors appeared of the form: ERROR 6: Unable to load PROJ.4 library (libproj.so), creation of OGRCoordinateTransformation failed.

Adding UseExceptions() at the beginning to catch the error resulted in the errors instead being masked. Attempting to use osr.CoordinateTransformation then resulted in a not so helpful error message: TypeError: in method 'Geometry_Transform', argument 2 of type 'OSRCoordinateTransformationShadow *'

Could you add a minimal python script for reproducing this behaviour?

Script attached. Hopefully the problem is clear. Basically, we want to stop the program with a clear error if there's a problem. We expected that UseExceptions would allow the error to be trapped but it actually caused the error to be masked.
