The error seems to be entirely from lxml. So I would guess that this is
an lxml issue not gnuradio related. Can you try to run python -c "from
lxml import etree" and see if the error happens?

*/I satisfied all the required dependencies with the build-gnuradio
script by SBRAC. Any ideas to solve this issue, it never happened to me
in any build of GNURadio from stable tarball. Do I have to install some
other python package ?
Thank you in advance
Kind Regards
Arturo

the python importing process (python -c "from lxml import etree") exits
without any error. I decided to switch to the 3.6.1 version from
quantal repos until the problem is solved. I tried to install different
versions of lxml from pipy but without any success.
