This looks like a problem with the interface to fftw.   Would you agree?

Pearu knows the most about this particular section of code.   It looks 
like his
module is generically calling the fftw library.  I don't know if all of 
the supported
routines have the same calling conventions.

Perhaps something else is going on to make it work with fftw.  Do fft's 
work with the default fft?

Do scipy.basic.fft and scipy.basic.ifft  from scipy core work as expected?
