 If you try and parse some invalid WKT (or do a number of other bad
 things), GEOS will throw an error you '''can't catch''' from Python,
 causing the interpreter to crash.

 {{{
 >>> from qgis.core import QgsGeometry
 >>> # WKT has a missing ')'
 >>> QgsGeometry.fromWkt("POLYGON((0 0, 1 0, 1 1, 0 0)")
 terminate called after throwing an instance of 'GEOSException'
 Aborted
 }}}

 ideally a developer should be able to catch it with:
 {{{
 >>> from qgis.core import QgsGeometry, GEOSException
 >>> try:
 >>>    QgsGeometry.fromWkt("POLYGON((0 0, 1 0, 1 1, 0 0)")
 >>> except GEOSException, e:
 >>>    print "uh oh, WKT error: %s" % e
 }}}
