I think I have found a fix.
The bug does not happen only with invalid UTF-8 filenames, you simply
need UTF-8 filenames and a UTF-8 locale.
For example, in collections.py:810, there is:
log.Debug(_("File %s is not part of a known set; creating new
set") % (filename,))
On my system, when this fails (see error below), the _() string is a str object
encoded in UTF-8; filename is a unicode object. The error below happens while
Python encodes filename into an ASCII str object. If the _() string is a
unicode object too, no encoding into a str object happens at this stage, and
everything works. This can be achieved by setting gettext up differently in
__init__.py, by passing unicode=True to gettext.install(). This is the solution
recommended by the author of gettext for Python:
http://www.wefearchange.org/2012/06/the-right-way-to-internationalize-your.html
This change requires a few modifications in other places so that only
unicode strings are passed to the logger. I'm attaching a diff of quick
and dirty changes I applied to demonstrate the idea.
Any chance to get some attention for this bug? This makes duplicity
completely unusable on my system for more than a year.
This is with duplicity 0.6.21 on Fedora 19.
