Need Help: new KHtmlPart crashes app

[Jan.Kaiser at OnVista.de]

Hello,

First of all: I am a newbie to KDE programming. So, please forgive me all
the stupid things in this mail.

My little program (code below) tries to access a DOM::Document from a html
page through KHTMLPart.document() method.
The program is a proof of concept of a "sloppy" HTML Dom Parser, which can
access the nodes of any HTML (not only XHTML) document (without
bringing up a GUI) and produce certain output.

The problem is that it exits with an instance of the KCrashManager that
reports the application exited with
SIGSEGV 11 and prints the following output:

This is the source:

#include <kapp.h>
#include <kurl.h>
#include <khtml_part.h>
#include <khtmlview.h>
#include <ostream.h>
#include <dom_doc.h>

int main(int argc, char* argv[])
{
  KApplication a(argc, argv, "test", false, false);
  cout << "created KApplication" << endl;
  KURL url = KURL("http://www.kde.org/index.php");
  cout << "created KURL" << endl;
  KHTMLPart *w = new KHTMLPart(); // this crashes
  cout << "created KHTMLPart" << endl;
  if (w != 0)
  {
    w->openURL(url);
    DOM::Document doc = w->document(); // at this point I will be lucky !!
  }
  else
    cout << "w is null" << endl;
  cout << "opened url" << endl;
  return a.exec();
}


Since I think there is only an error in the creation of the KApplication /
KHTMLPart I hope
the problem can be found easily.


Thanks in advance, Jan
