This explains it, thanks.

You're missing several updates to the TOhtml plugin, including the version which adds html_pre_wrap:

" 7.3_v12 (this version): Fix modeline mangling to also work for when multiple
" highlight groups make up the start-of-modeline text.
" Improve render time of page with uncopyable regions
" by not using one-input-per-char. Change name of
" uncopyable option from html_unselectable to
" html_prevent_copy. Added html_no_invalid option and
" default to inserting invalid markup for uncopyable
" regions to prevent MS Word from pasting undeletable
" <input> elements. Fix 'cpo' handling (Thilo Six).
" 7.3_v12b1: Add html_unselectable option. Rework logic to
" eliminate post-processing substitute commands in
" favor of doing the work up front. Remove unnecessary
" special treatment of 'LineNr' highlight group. Minor
" speed improvements. Fix modeline mangling in
" generated output so it works for text in the first
" column. Fix missing line number and fold column in
" diff filler lines. Fix that some fonts have a 1px
" gap (using a dirty hack, improvements welcome). Add
" "colorscheme" meta tag. Does NOT include support for
" the new default foldtext added in v11, as the patch
" adding it has not yet been included in Vim.
" 7.3_v11 ( unreleased ): Support new default foldtext from patch by Christian
" Brabandt in
" http://groups.google.com/d/topic/vim_dev/B6FSGfq9VoI/discussion.
" This patch has not yet been included in Vim, thus
" these changes are removed in the next version.
" 7.3_v10 (fd09a9c8468e): Fix error E684 when converting a range wholly inside
" multiple nested folds with dynamic folding on.
" Also fix problem with foldtext in this situation.
" 7.3_v9 (0877b8d6370e): Add html_pre_wrap option active with html_use_css
" and without html_no_pre, default value same as
" 'wrap' option, (Andy Spencer). Don't use
" 'fileencoding' for converted document encoding if
" 'buftype' indicates a special buffer which isn't
" written.
" 7.3_v8 (85c5a72551e2): Add html_expand_tabs option to allow leaving tab
" characters in generated output (Andy Spencer).
" Escape text that looks like a modeline so Vim
" doesn't use anything in the converted HTML as a
" modeline. Bugfixes: Fix folding when a fold starts
" before the conversion range. Remove fold column when
" there are no folds.
" 7.3_v7 (840c3cadb842): see betas released on vim_dev below:
" 7.3_v7b3: Fixed bug, convert Unicode to UTF-8 all the way.
" 7.3_v7b2: Remove automatic detection of encodings that are not
" supported by all major browsers according to
" http://wiki.whatwg.org/wiki/Web_Encodings and
" convert to UTF-8 for all Unicode encodings. Make
" HTML encoding to Vim encoding detection be
" case-insensitive for built-in pairs.
" 7.3_v7b1: Remove use of setwinvar() function which cannot be
" called in restricted mode (Andy Spencer). Use
" 'fencoding' instead of 'encoding' to determine by
" charset, and make sure the 'fenc' of the generated
" file matches its indicated charset. Add charsets for
" all of Vim's natively supported encodings.

You can fix it in three different ways:

1. Install the latest Vim (probably from source) including the latest runtime file updates.
2. Get the latest runtime files for just TOhtml and stick them in ~/.vim to override the old ones in your distribution (just remember to remove them when you upgrade you distribution). They are intended to work with older Vims as well. You will need:
http://code.google.com/p/vim/source/browse/runtime/autoload/tohtml.vim
http://code.google.com/p/vim/source/browse/runtime/plugin/tohtml.vim
http://code.google.com/p/vim/source/browse/runtime/syntax/2html.vim
and optionally (for the documentation):
http://code.google.com/p/vim/source/browse/runtime/doc/syntax.txt
3. Use the html_no_pre option instead of html_pre_wrap. This will remove the <pre> tag from the output, which will allow text wrapping. But it can also cause it to not look as nice. With an appropriate colorscheme and font, it should not be too much of a problem.
