Having built sysutils/nepomuk-core with base clang now, it shows up a bug in
qt4-corelib, where QTextCodec::codecForLocale () returns an invalid
QIconvCodec instance to QTextStream's flushWriteBuffer member procedure which
is called by the destructor on application's termination.

Most probably this happens because the QIconvCodec instance has already been
destroyed at this point.

Btw, even if I define my language settings (LANG, LC_ALL, ...) accordingly and
have chinese/qt4-codecs-zh, japanese/qt4-codecs-jp, ... installed, I still
get the QIconvCodec from QTextCodec::codecForLocale(), which makes me wonder
whether these ports are good for FreeBSD-8/9 only or maybe not required at all
any more?
