[SOLVED] libxml2 2.9.1.-4 includes a malfunctioning Python 3 module

The libxml2 2.9.1.-4 update has broken Python 3. E.g. if you start newsfeed (from AUR), you get:

  File "newsfeed", line 19, in <module>
    from newsfeed import *
  File "/home/martin/git/3NewsFeed/newsfeed.py", line 30, in <module>
    import feedparser, rssfinder, dlthreads, play_wav
  File "/home/martin/git/3NewsFeed/feedparser.py", line 199, in <module>
    xml.sax.make_parser(PREFERRED_XML_PARSERS) # test for valid parsers
  File "/usr/lib/python3.3/xml/sax/__init__.py", line 78, in make_parser
    return _create_parser(parser_name)
  File "/usr/lib/python3.3/xml/sax/__init__.py", line 102, in _create_parser
    drv_module = __import__(parser_name,{},{},['create_parser'])
  File "/usr/lib/python3.3/site-packages/drv_libxml2.py", line 68
    except ImportError, e:
                      ^
SyntaxError: invalid syntax

Reverting to libxml2 2.9.1-3 helps, but I still wanted to report this somewhere.

Bugs should be reported in the bugtracker, not on the forum.

How exactly is this worse than before? We used to have no py3 module at all.

And does it work after you run "2to3 -w /usr/lib/python3.3/site-packages/{drv_,}libxml2.py"?

As a workaround you can downgrade to libxml2-2.9.1-3

I used:

sudo pacman -U /var/cache/pacman/pkg/libxml2-2.9.1-3-x86_64.pkg.tar.xz

Should be something similar on your system.
