// It is very important to make the archive dialog a child of the KHTMLPart!

// while archiving runs @c part becomes invalid. Furthermore the various @ref QHash<>
// members of @ref ArchiveDialog contain DOM elements that use ref counting. Upon
// exit of Konqueror @c part gets destroyed *before* our @ref ArchiveDialog . Since
// our running ArchiveDialog keeps the DOM ref counts up KHTML triggers an assertion
// in KHTMLGlobal
//
// In contrast if @ref ArchiveDialog is a child of the part view Qt ensures that all
// child dialogs are destroyed _before_ @c part is destroyed.
