tex4ht ends with an error when compiles biblatex files. I'm on Windows, texlive 2012. I put here a minimal example and files generated with the command latexmk test && mk4ht oolatex test
https://www.dropbox.com/s/hn1zm40htqs13mf/t4htlink.zip There is a superfluous \relax in the file test.tmp, line 65 which seems to cause the error. Cheers, Oleg
