Investigating this issue a bit more, I found that a return_if_fail was added to
g_file_test in 2017-04-08 and Arch is building the glib package from a
commit of 2017-06-01. Now I know why some guys from Manjaro and I are getting
this message, but I wonder if we should just ignore NULL file paths or fix the
source of problem (if there's one).
