New submission from Alexander Maksimenko <alex.mclander at gmail.com>:

mimetypes.py(249) expectts Unicode*En*codeError, but Unicode*De*codeError happens when registry has non latin symbols (Vista Home 64).

I just change cathc jn next line to UnicodeDecodeError and all now works fine. But may be error not here, but on encode method which raise "negative" exception

F:\>c:\python27\python -m SimpleHTTPServer
Traceback (most recent call last):
  File "test.py", line 2, in <module>
    import SimpleHTTPServer
  File "c:\python27\lib\SimpleHTTPServer.py", line 27, in <module>
    class SimpleHTTPRequestHandler(BaseHTTPServer.BaseHTTPRequestHandler):
  File "c:\python27\lib\SimpleHTTPServer.py", line 204, in SimpleHTTPRequestHandler
    mimetypes.init() # try to read system mime.types
  File "c:\python27\lib\mimetypes.py", line 355, in init
  File "c:\python27\lib\mimetypes.py", line 259, in read_windows_registry
    for ctype in enum_types(mimedb):
  File "c:\python27\lib\mimetypes.py", line 249, in enum_types
    ctype = ctype.encode(default_encoding) # omit in 3.x!
UnicodeDecodeError: 'ascii' codec can't decode byte 0xe0 in position 0: ordinal not in range(128)
