Ouch! That looks like another variation on a bug of which we've fixed at
least two variations to do with reading mimetypes from the Windows
registry. Can you see what the following code produces, please:
<code>
import winreg as _winreg
hkcr = _winreg.OpenKey(_winreg.HKEY_CLASSES_ROOT, "")
with open("classes.txt", "w") as f:
i = 0
while True:
try:
ctype = _winreg.EnumKey(hkcr, i)
except EnvironmentError:
break
else:
f.write("%s -> %r\n" % (type(ctype), ctype))
i += 1
</code>
