Here is the code in short:

   settings = QSettings('Pandoc', 'PanConvert')

   path_pandoc = settings.value('path_pandoc','')




   if not os.path.isfile(path_pandoc):




       if platform.system() == 'Darwin' or os.name == 'posix':

           args = ['which', 'pandoc']

           p = subprocess.Popen(

               args,

               stdin=subprocess.PIPE,

               stdout=subprocess.PIPE)




           path_pandoc =
str.rstrip(p.communicate(path_pandoc.encode('utf-8'))[0].decode('utf-8'))


The whole problematic code can be checked on
http://github.com/apaeffgen/panconvert
in source/converters/interface_pandoc.py


Checking your repo I found that get_path_pandoc, the function from which 
you took the code snippet above, will always return None if 
os.path.isfile(path_pandoc).

This is probably not what you are intending. Do you know if path_pandoc 
is maybe set to an existing file in your frozen code already so the 
whole 'which' or 'where' branch is never executed?

Best,
Wolfgang
