Interrupting Task in 0.4 vs 0.5+

Interrupting task in 0.4 used to fail gracefully, while in 0.5+ it freezes the REPL in some situations, e.g:

0.4.7 :

julia> t = @schedule begin
           try
               remotecall_fetch(1,sleep,100)
           catch err
               rethrow(err)
           end
       end
Task (waiting) @0x000000010fb39a50

julia> Base.throwto(t, InterruptException());

For context, I’m getting this kind of issues when using Gtk.jl, in which case interrupting any task makes Gtk crash in 0.5+.

Is this a bug or is there a way to get back 0.4 behaviour (by handling the error or interrupting differently) ?
