I was told that it's quite likely a bug in Deluge caused by alerts-related
code change in libtorrent 1.1.0. Direct link to a comment with
explanation:

* milestone: needs verified => 1.3.16
Comment:
I have fixed the issue in develop code [be74d96c6a6] but I am not sure if
I will backport to 1.3 as I have stated that 1.3 does not support
libtorrent versions >= 1.0
