I updated kdelibs today and noticed that *voila* everything crashes.
The backtrace is something like this:

-----------------------------------------------------------------------

-----------------------------------------------------------------------

Now I haven't changed Qt or X in a while so I doubted that it was #0 -
#5.  So I messed around with versions and found the problem to be in
klocale.cpp version 1.273.  It's this change:

   void KLocale::initCharset(KConfig *config)
   {
  -  KConfigGroupSaver saver(config, "Locale");
  -  m_charset = config->readEntry("Charset");
  -
  -  if (m_charset.isEmpty())
  -    {
  -      m_charset = QString::fromLatin1("iso-8859-1");
  -    }
  -  else
  -    {
  -      // ### HPB: This code should be rewritten/removed
  -      bool bOk;
  -      KGlobal::charsets()->codecForName(m_charset, bOk);
  -      // if !ok, we have a problem. it will return latin-1 then, but thats
  -      // obviously not what the user wants
  -      if(!bOk)
  -       kdWarning(173) << "charset " << m_charset
  -                      << " is not known. using ISO 8859-1 instead." << endl;
  -      //m_charset = QString::fromLatin1("iso-8859-1");
  -    }
  +  m_charset = KGlobal::charsets()->charsetForEncoding(encoding());

If I revert it, then everything is honky-dory.  With it *nothing*
works.

Is it just me?
