1.3.14 fails to respond properly to choosing which files one wants to download.

1.3.14 fails to respond properly to choosing which files one wants to download from within a torrent.

For example, I start a torrent but only want to download 5 of the 50 files within the torrent so I high-light those I do NOT want and choose "Do Not Download." Note that Deluge 1.3.14 has a lot of difficulty designating the files as "Do Not Download" and several attempts are often necessary...

Expected behaviour is that Deluge will ignore those files designated as "Do Not Download", and only download the files designated as "Normal, High, or Highest" priority.

What occurs: Deluge completely messes it up, and files that are designated "Do Not Download" are downloaded; files that are designated "Normal Priority" etc. are only partially downloaded, or not at all.

Also, if the 50 files have a total size of 50MB, and the files designated "Normal Priority" etc., have a total size of 5MB, the "Size" column will read some random number that is much larger than the expected 5MB. Running a Force ReCheck? does nothing to fix it. It is a total disaster.

Installed via ppa on Xubuntu Xenial. I have confirmed this on both my Xenial systems.

Purged ppa and returned to 1.3.12 and everything works fine.

Yes I need to investigate what went wrong with the backported priorities patch but thanks for details. Already reported in #2990
