TypeError: converter.AsyncConvertData is not a function

I'm getting this error in Deer Park. In FF 1.04 the function works fine.
Here's the code:

var converter =
Components.classes['@mozilla.org/streamconv;1?from=gzip&to=uncompressed'].createInstance(Components.interfaces.nsIStreamConverter);
var list = new dataListener(outFile, dest);
converter.AsyncConvertData("gzip", "uncompressed", list, null); 

Reproducible: Always

ok, two things:
1) to get an nsIStreamConverter, you should use the nsIStreamConverterService

2) AsyncConvertData was renamed to asyncConvertData. to find out which version
the current build is using, you can do:

if ("AsyncConvertData" in converter)
  converter.AsyncConvertData("gzip", "uncompressed", list, null); 
else
  converter.asyncConvertData("gzip", "uncompressed", list, null); 

However, if you use nsIStreamConverterService, you need not do that. the method
there didn't change its name.

This is not a bug.

oops, sorry, that is not true. it also changed its name after 1.0.x branched,
although at a different point in time. so you still need code similar to what I
wrote above.

ok, the renaming worked. Thank you very much!
