So, in order to "bring it back to life" till the team fix this bug we have to do the following...
-Completely remove this packages: deluge, deluge-common, deluge-core, python-chardet, libtorrent-rasterbar2, python-libtorrent.
-Disable the PPA repos, in order not to get the last version again.
-Install Deluge with all the dependencies again.
At this step Deluge must been working again, you'll have the 1.1.6 version, but it'll work.
Now if you still want the 1.1.8 because of the bugfixes and the other improvements...
-Enable the PPA repos again, and update the "deluge" package, it will force you also to update the deluge-common, deluge-core and to install the "python-chardet". Till this step my Deluge is still working, but just in case, I forced the libtorrent-rastebar2 and the python-libtorrent to remain on the 0.14.2-2 version, as i've said before, till this bug gets fixed
