I am attaching the bug.org file and the html exports as done by git
versions 048f32 (approx a month old) and 77c278 (very recent).

Put the html file in nxml-mode and do a C-c C-n to check for validation
errors.

Click on the associated links in the html browser and you would notice
that there is a regression.

I don't haven't tried git bisection. I hope someone fixes these
regressions & malformed htmls.
