Comment 17 for bug 174373

I did
cd /usr/local/lib
sudo rm libpango*
(to remove all files with name beginning by libpango)

cd /usr/local
sudo rm -r pango

sudo apt-get install --reinstall libpango1.0-0 libpango1.0-common
cd /home/myuser/
checked which files were with pango in the name, with
ls -a
then did
sudo rm -r pango-1.20.5

Mind that this exact sequence won't work with you if pango was not installed in the same places.
Hope it helps,
