 I've found a workaround for this issue. It allows the build to
 complete with Python 3.5, and is apparently a no-op for Python 3.4
 (I tested with both). With the build complete, the Python 3.5 version
 passes its test suite successfully (once one of the test files has
 its interpreter invocation corrected). See also my comments in the
 upstream bug report:
 
 https://bugs.freedesktop.org/show_bug.cgi?id=3D76759
 
 The patch is:
 
 With Python 3.5, uncaught exceptions thrown by this code block would
 cause the build to fail. The exceptions seem to be harmless: they
 don't prevent the build from succeeding.
