OK, thanks for your sources.
This problem is fixed by doing 2 things
A. a 1-line bug-fix in sub process_undefined_environment
Find the lines starting
$contents = "\n% latex2html id marker $id\n$contents" if
and insert on the next line:
(!$PREAMBLE &&($contents=~ ......
^^^^^^^^^^^^^____insert this
B. use \protect either in the caption: $\protect\R$
or in the definition of \R , i.e. as \protect\mathbb{R}
Either should work.

The point is that if you are using amsmath then you should be using
the high-powered math-parsing offered by the `math' extension.
The smaller images that it generates give better down-load times.
Also, the HTML markup better reflects the logical content
of the mathematics, much more so than does a single large image.
Searching on sub-expressions becomes possible.

Yes, \raisebox isn't being handled correctly within math-parsing.
To force an image, change your \newcommand definition to:
\newcommand{\smgt}{\mbox{$\scriptstyle>$}}
You won't get the \raisebox this way, though.
That'll have to wait till I decide how it should be handled;
e.g. via an image --- otherwise the raising will not be evident.

You're welcome.
