Pydub from_mp3 gives [Errno 2] There is no such file or directory

Question

I find myself facing a wall here, just trying to load an audio file into pydub to convert it, it keeps throwing the error "[Errno 2] No such file or directory".

Naturally, I spent too much time making sure that the paths are valid, tried relative and absolute paths, and confirmed that the python open () method works fine with the same path as it is.

I am working in ipython 3.2 with python 2.7 through the anaconda 2.3 distribution on ubuntu.

from pydub import AudioSegment
sound = AudioSegment.from_mp3("/absolute/path/to/file.mp3")

Also tried without spaces in the way, as this is sometimes a problem. Here is the complete error log:

Am I blind to something really simple or ...?
