Bug: When running any Psychopy experiment, OpenSesame crashes with the following message:
Error: OpenExp error
Description: Failed to call openexp._canvas.psycho.init_display()

Error: 'pygame.Surface' object has no attribute 'set_caption'

(there is no stacktrace in the debug window)

Edit: This could occur because my pyglet installation seems faulty, which is weird, as I just use the standard Ubuntu pyglet installation. OpenSesame probably falls back to pygame as a window manager and then errors occur.
My pyglet problem is as follows:

>>> pyglet.window.Window()
Traceback (most recent call last):
  File "", line 1, in 
  File "/usr/local/lib/python2.7/dist-packages/pyglet/window/xlib/__init__.py", line 474, in __init__    super(XlibWindow, self).__init__(*args, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/pyglet/window/__init__.py", line 641, in __init__    raise NoSuchConfigException('No standard config is available.')
NoSuchConfigException: No standard config is available.

I looked this error up on Internet and it appears to have to do with NVidia videocards and drivers (http://code.google.com/p/pyglet/issues/detail?id=456; it status says solved, but appararently it isn't). Since NVidia gpus are very common it is likely more people will bump into this problem, so I found it worth to mention this pyglet error here.

Thanks, yes, This is not a bug in OpenSesame per se, but somewhere downstream. So there's unfortunately not much that we can do about it. I'll add a try ... except statement around the part where the window caption is set. That will work around this particular error, but presumably there will be other problems as well.

Btw, it is not OpenSesame that falls back to PyGame, but PsychoPy: https://github.com/psychopy/psychopy/blob/d160ebde9bd53b40b8a259ddd9d890cf130f00e1/psychopy/visual.py#L272

Have you tried what happens if you update PsychoPy? You can get the latest version for Ubuntu via the NeuroDebian repo. (It will probably crash as well, but just to find out what happens exactly.)
