It definitely is fixed in 0.7.7. I reconverted a bunch of my Mobi books to ePub with 0.7.7, checked them, and they all had "<dc:language>en</dc:language>" in the OPF.
Take a look inside one of your ePUb files (rename it to ".zip", open it, and look at the file with the ".opf" extension). What is the value of the "<dc:language>" tag?
