Well it has definitely to do with the length of the file. If the file is to short the the loading function will not work properly. Just prolong your file and it will work. Shrink an working file under 0,5 sec and the error will show up.
P.S: the magic limit seems to be 0,57-0,58 sec with 22050Hz 16-bit.
P.P.S: okay seems to be file dependend
