[Kde-bindings] Simple KCrash question

[Martin Welch]

I, er, pinched this from the first kde3 app I found on kde.org to see
how to do this. As you can see I've not changed it yet.

I wondered if it's a) because I'm creating more than one top level
window which the X server is unhappy with or b) it's a multi threading
issue.

If I unravel the code essentially I'm trying two things:

First, 

CMainWindow::polish() // corresponds to SWF Form.Load
{
	KMainWindow* w = new KMainWindow(0, "test", WDestructiveClose);
	w->show();
}

This works and creates the "test" main window before the main app
window.

However, if I connect a KPopupMenu like this:

void CMainWindow::Connect(KPopupMenu* pMenu)
{
	connect( pMenu, SIGNAL(activated(int)), SLOT(OnActivated(int))
);
}

void CMainWindow::OnActivated(int id)
{
	KMainWindow* w = new KMainWindow(0, "test", WDestructiveClose);
	w->show();
}

The fault occurs in the KMainWindow c-tor in OnActivated. The difference
is that the main window is now visible - exec() is executing.

Thanks for your help Richard.

It looks like KAboutData::programName() is returning a null string or 
something. So you probably haven't set it up correctly in the KAboutData

constructor - can you post the code here? It should take three strings 
appName, programName and version.
