TypeError: must be string, not int

In a freshly installed Debian (2015-03-01) on Beaglebone Black Rev A6A, the encoder_test.py example shows this error:

Code is wrong at time.sleep(ms/1000), is ms previously defined. Check for
that because sleep function takes int.

I have not changed anything in the example. It is in integer already. The error says "must be String" -- I'm also confused at this.
Here is the code

#!/usr/bin/env python
"""
 encoder_test.py
 Rekha Seethamraju

 An example to demonstrate the use of the eQEP library
 for PyBBIO.

 This example program is in the public domain.
"""
from bbio import *
from bbio.libraries.RotaryEncoder import RotaryEncoder

encoder = RotaryEncoder(RotaryEncoder.EQEP2b)

def setup():
  encoder.setAbsolute()
  encoder.zero()

def loop():
  print "encoder position : \t"+encoder.getPosition()
  delay(1000)

run(setup, loop)

Hmm... this is an odd one. Seems that either the RotaryEncoder library itself or the sysfs C extension it uses to read/write the eQEP driver files is the source of the problem (time.sleep most certainly doesn't take a string!). I'm looking into it...

Just letting you know I'm having the exact same problem with the same code
I'm on Beaglebone Black Rev C. Version is:
Linux beaglebone 3.8.13-bone70 #1 SMP Fri Jan 23 02:15:42 UTC 2015 armv7l GNU/Linux

Any new ideas on this yet? I'm stuck

[alexanderhiam]

OK got it, I was missing a type check in a C extension, and the TypeError was popping up at a weird time.
