After some debugging it turns out, that the win32 wma codec crashes, after it 
is called with illegal (it seems unitialized) parameters.

To compare, here's a backtrace of a correctly working file:
Opening audio decoder: [acm] Win32 ACM audio decoder
======= Win32 (ACM) AUDIO Codec init =======
Input format:
  wFormatTag 353
  nChannels 1
  nSamplesPerSec 22050
  nAvgBytesPerSec 2003
  nBlockAlign 651
  wBitsPerSample 16
  cbSize 10
Output fmt:
  wFormatTag 1
  nChannels 1
  nSamplesPerSec 22050
  nAvgBytesPerSec 44100
  nBlockAlign 2
  wBitsPerSample 16
  cbSize 0
Loading DLL: 'divxa32.acm'
Audio codec opened OK! ;-)

Now the backtrace from above mentioned bad file:
Opening audio decoder: [acm] Win32 ACM audio decoder
======= Win32 (ACM) AUDIO Codec init =======
Input format:
  wFormatTag 353
  nChannels 1
  nSamplesPerSec 22050
  nAvgBytesPerSec 2519
  nBlockAlign 117
  wBitsPerSample 16
  cbSize 10
Output fmt:
  wFormatTag 1
  nChannels 1
  nSamplesPerSec 22050
  nAvgBytesPerSec 44100
  nBlockAlign 2
  wBitsPerSample 16
  cbSize 0
Loading DLL: 'divxa32.acm'
Audio codec opened OK! ;-)

^^^^^^ params here seem invalid (uninitalized?)
