This fixes the linker error:

Maybe it is better to declare the export in dbus and
to include in kconfigbase.h the dbus header.



And the instantiation comes from:

template <typename T>
inline QList<T> KConfigBase::readEntry( const char* pKey, const QList<T>& aDefault) const
{
  QVariant::Type wanted = QVariant(T()).type();
#if KCONFIG_QVARIANT_CHECK
  ConversionCheck::to_QVariant<T>();
  ConversionCheck::to_QString<T>();
#else
  kcbError(!QVariant(QVariant::String).canConvert(wanted))
    << "QString cannot convert to \"" << QVariant::typeToName(wanted)
    << "\" information will be lost" << endl;
#endif

  if (!hasKey(pKey))
    return aDefault;

  QList<QVariant> vList;

  if (!aDefault.isEmpty()) {
    foreach (T aValue, aDefault)
      vList.append( aValue );
  }
  vList = readEntry( pKey, vList );

  QList<T> list;
  if (!vList.isEmpty()) {


Each call to this readEntry instantiates at least the ctor and dtor
of QList<QVariant>. I don't know a other solution than importing
the QList<QVariant> code.
