Hi :)
I'm using latest flexget from git on develop branch on gentoo linux ~amd64 with Python 3.5.5

running flexget check returns no warnings or errors
after I enabled the guessit plugin for series when I run a task i named tv-sort, for sorting my tv-shows, flexget crashes.

the crash report is at https://paste.pound-python.org/show/FzJA3quGxCUg6iS0CJmt/
my config.yml is at https://paste.pound-python.org/show/fj7yoiAsyBSlujXyVfVa/

thanks! :)
