Comment 11 for bug 1286836

I used the tip from (cwwitt) to solve my problem and it worked.

" Workaround :
sudo dpkg --purge libpostproc52:i386

Then reinstall libpostproc52.
"
or in other words
sudo apt-get purge libpostproc52:i386
sudo apt-get install libpostproc52

worked for me too "

As if by magic, my problem is over, thanks for the hint and all the best to you!
