Dropdown lists don't work

[Martijn vdS]

When I open a dropdown list, this shows up in my terminal, and the dropdown is empty:

Traceback (most recent call last):
  File "/usr/lib/blender/scripts/modules/bpy_types.py", line 719, in draw_preset
    filter_ext=lambda ext: ext.lower() in {".py", ".xml"})
  File "/usr/lib/blender/scripts/modules/bpy_types.py", line 681, in path_menu
    import bpy.utils
ValueError: level must be >= 0

I think it might be releated to http://bugs.python.org/issue15610

The precompiled Blender 2.65a from blender.org does not have this problem with its bundled Python.

I believe this was python problem. anyway Ubuntu 13.04 was EOLed so I mark this bug as invalid.
