I had the same error on Mythbuntu 12.04 and for me it was caused by the
target user (mythtv) attempting to write to the logged-in user's home
directory (not mythtv) to create the initial config file. I changed the
test command to the following and it worked as expected:

sudo -u mythtv -H lossless_cut -f "/path to a/recorded.mpg" --test

The '-H' sets the HOME variable to that of the target user. This probably
doesn't affect everyone because you can configure this to be the default
behavior of sudo if you wish.

Also, I have version 2.3.2-1 for the package python-lxml installed and
things seem to be OK. One of my recordings triggers a runaway memory leak
in mkvmerge, but otherwise everything has been working well.
