Dear Radhakrishnan,
Attached is a newer version of biblatex.4ht. It works fine with the example provided in your post. Also, it runs with Christian's (OP) test document in my system. If the new version works fine in your setup, I shall update the SVN with necessary notes.
The new version runs perfectly both for my test cases and the files I apply it usually - thank you very much!
