RecursionError when looping DataMatrix

SpacePenguins

Hi,

When I do a simple loop over a DataMatrix object in OpenSesame I get: RecursionError: maximum recursion depth exceeded.

Code:

from datamatrix import DataMatrix

dm = DataMatrix(length=5)
dm.fibonacci = 0, 1, 1, 2, 3
for row in dm:
  print(row.fibonacci)

Error:

I tried it on another computer and it worked.

I think it have something to do with my installation/computer because if I use the PsychoPy back-end it crashes and looks like this:

I have tried many different version of Opensesame and it never works. But I had more success with pygames as the back-end, until I ran into this problem.
