Bug Description

Duplicity fails to report correct exception when run in non-ascii locale. For example, if python-boto dependency is not installed and I attempt any operation involving interaction with Amazon S3, it fails with non-descriptive error:
Traceback (most recent call last):
  File "/usr/bin/duplicity", line 1538, in <module>
    log.FatalError(u"%s: %s" % (e.__class__.__name__, util.uexc(e)),
  File "/usr/lib/python2.7/dist-packages/duplicity/util.py", line 76, in uexc
    return ufn(str(e))
UnicodeEncodeError: 'ascii' codec can't encode characters in position 0-9: ordinal not in range(128)

This error can be easily fixed by replacing body of the uexc function in the utils module with the following statement:
return ufn(unicode(e).encode('utf-8'))

I'm using duplicity 0.6.23 (the code is the same in the latest version of duplicity) on Ubuntu 14.04.

This doesn't work for me, unfortunately. I got the same error.
