Please forgive me is this is the wrong place to ask; it appears that RSSOwl [GitHub] is 'dead,' so I am hoping for an answer here.

Any time RSSOwl tries to open a PDF file link, RSSOwl freezes. I have to kill / restart RSSOwl

RSSOwl: v.2.2.1 | Build Id: 2013-12-30
OS: Arch Linux x86_64
Linux kernel: v.4.6.4-1

Otherwise, RSSOwl works great! :-)
