What does your Hunspell say when you invoke it with -D?  Mine says
this:

  SEARCH PATH:
  
.;;C:\Hunspell\;D:\usr\eli\.openoffice.org\3\user\wordbook;D:\usr\bin\..\share\hunspell;C:\Program
 files\OpenOffice.org 2.4\share\dict\ooo\;C:\Program files\OpenOffice.org 
2.3\share\dict\ooo\;C:\Program files\OpenOffice.org 
2.2\share\dict\ooo\;C:\Program files\OpenOffice.org 
2.1\share\dict\ooo\;C:\Program files\OpenOffice.org 2.0\share\dict\ooo\
  AVAILABLE DICTIONARIES (path is not mandatory for -d option):
  D:\usr\bin\..\share\hunspell\american
  D:\usr\bin\..\share\hunspell\default
  D:\usr\bin\..\share\hunspell\de_AT
  D:\usr\bin\..\share\hunspell\de_CH
  D:\usr\bin\..\share\hunspell\de_DE
  D:\usr\bin\..\share\hunspell\de_DE_frami
  D:\usr\bin\..\share\hunspell\ENU
  D:\usr\bin\..\share\hunspell\en_GB
  D:\usr\bin\..\share\hunspell\en_MED
  D:\usr\bin\..\share\hunspell\en_US
  D:\usr\bin\..\share\hunspell\he_IL
  D:\usr\bin\..\share\hunspell\russian
  D:\usr\bin\..\share\hunspell\ru_RU
  D:\usr\bin\..\share\hunspell\sv_SE
  LOADED DICTIONARY:
  D:\usr\bin\..\share\hunspell\default.aff
  D:\usr\bin\..\share\hunspell\default.dic
  Hunspell 1.3.2

Note that the default dictionary it loaded, as announced near the end.

Once again, I ask where you got your Hunspell binary.  In the binary
distribution here:

  
http://sourceforge.net/projects/ezwinports/files/hunspell-1.3.2-3-w32-bin.zip/download

which is what I use, there's the "default" dictionary, in the form of
2 files: default.dic and default.aff.  Do you have them in your
share/hunspell/ directory?  If not, just copy your "usual" dictionary
files into those names (or toss your Hunspell installation and use
mine instead ;-).

I see no bug here.  It works for me.  I think your Hunspell
installation is misconfigured, that's all.
