the real problem is the paragraph with numbers after the end of
document. I've found the source of this problem:
it's `\blx@checksum`, which is defined with three parameters in
biblatex2.sty, but without parameters in biblatex.4ht, so these
parameters are rendered in the output. So it seems that this should be
fixed in biblatex.4ht. As quick fix, add this definition to your .cfg
file:
\def\blx@checksum#1#2#3{}
After this change, I can compile your document using oolatex and it
seems quite OK, on first sight.
Best,
Michal
