There should exist a fix to the meld3 which causes the problem with the line:
"from xml.etree.ElementTree import fixtag"

I havent found the fix, but used the following workaround (in a terminal) :

sudo apt-get install python-setuptools
sudo apt-get install python-setuptools
sudo easy_install elementtree
