Comment (by jhpalmieri):

 With or without Nathann's patch, we should fix the actual bug:
 {{{
 #!diff
 diff --git a/sage-ptest b/sage-ptest
 --- a/sage-ptest
 +++ b/sage-ptest
 @@ -429,6 +429,7 @@ for gr in range(0,numglobaliteration):
      interrupt = False

      numthreads = min(numthreads, len(files))  # don't use more threads
 than files
 +    numthreads = max(numthreads, 1) # use at least one thread

      if len(files) == 1:
          file_str = "1 file"
 }}}
 although as Leif says we could also give a warning if no files will be
 tested, and also a warning about the hidden directory issue. For example:
 {{{
