this pkg contains six chinese fonts. gkai00mp.ttf and gbsn00lp.ttf are for simplified chinese; bkai00mp.ttf and bsmi00lp.ttf are for traditional chinese; These four fonts are out of date. we know use uming.ttf and ukai.ttf. A new version has release a month ago,but in the portage it is still 20060503. I do not think a new version font can bring unstable.
Thanks for reporting, uming.ttf and ukai.ttf are now bumped to latest version available.
