Start with awsshell/utils.py at remove_html and follow its caller in awsshell/makeindex.py, especially the indexing path shown in the traceback. Reproduce the first-run aws-shell failure on the reported Python 2.6 environment, then verify that autocomplete index creation completes without the HTMLParser exception.
