PDFMiner3k: Maximum recursion depth exceeded while calling a Python object

[csyezheng]

maximum recursion depth exceeded error when using pdfminer3k
Here is my code:

def readPDF(path):

rsrcmgr = PDFResourceManager()
retstr = StringIO()
laparams = LAParams()
device = TextConverter(rsrcmgr, retstr, laparams=laparams)

with io_open(path, 'rb') as pdfFile:
    process_pdf(rsrcmgr, device, pdfFile)
device.close()

content = retstr.getvalue()
retstr.close()

filename = path.replace('pdf', 'txt')
with open(filename, 'w') as f:
    f.write(content)

This is the error received:
