I can confirm. I sent a mail to Lubos about it last Tuesday, but I think he's on vacations currently ;)

Here's what I said: there's a kde-commits answer mail (*) which crashes khtml because of Japanese in a .desktop file being quoted, I think:

Hmm I first got a nice gdb backtrace with QFontDatabase loading a font (using loadFontConfigFont())
with script=QFont::Han_Japanese. But now I lost it and when I retry I only get a crap bt, strange.
