[boost] [hs] Quickbook highlighting doesn't work in KDE 4.3

I'm not sure it's the right place for this, so sorry if it's off-topic. I'm trying to use Boost.HS* with Kate from KDE 4.3 on Ubuntu 9.04 but it doesn't work. There appears no "boost::hs" group in the Toost->Highlighting menu, neither does it color the quickbook files. Have anyone run into such kind of problems? PS: I successfully used Boost.HS with previous KDE versions (4.1 for sure, not sure about 4.2). This tool really helps to document the library, many thanks to the author. * http://www.drivehq.com/web/matias.capeletto/boost_hs/doc/html/index.html
