New crash information added by DrKonqi

umbrello (2.6.2) on KDE Platform 4.6.2 (4.6.2) using Qt 4.7.2

- What I was doing when the application crashed:
1. Clicked on a class which was not on the diagram but in the UML Model tree view. 
2. Opened its properties dialog with right-click.
3. Copied and pasted the package name for the class. It was empty before.
4. Clicked OK.
5. Application crashed.

Comment 3 Ralf Habacker 2011-12-08 11:55:33 UTC
same issue her (In reply to comment #2)

could be reproduced on windows using msvc
Comment 4 Ralf Habacker 2011-12-08 12:13:49 UTC
at least on windows the problem occurs by an overwritten UMLListViewItem object. 

in the current item is requested. 

void UMLListView::popupMenuSel(QAction* action)
    UMLListViewItem * temp = (UMLListViewItem*)currentItem();

later the property dialog is displayed: 

        if (Model_Utils::typeIsCanvasWidget(lvt)) {

after calling dlg->exec() 

bool UMLObject::showProperties(int page, bool assoc)
    DocWindow *docwindow = UMLApp::app()->docWindow();
    QPointer<ClassPropDlg> dlg = new ClassPropDlg((QWidget*)UMLApp::app(), this, assoc);
    bool modified = false;
!!!    if (dlg->exec()) {

then at least the following object members of 'temp' are overwritten 

+		m_label	{d=0x00000000 }	QString
+		m_comap	{d=0xfdfdfdfd e=0xfdfdfdfd }	QMap<UMLClassifierListItem *,UMLListViewItem *>

After pressing "ok" in the property dialog the widget is going to be moved to the other package, which is handled in 

>	umbrello.exe!UMLListView::moveObject(std::basic_string<char,std::char_traits<char>,std::allocator<char> > srcId, 

In fact a new widget is created and the old one deleted  

    case UMLListViewItem::lvt_Datatype:
        if (newParentType == UMLListViewItem::lvt_Logical_Folder ||
                newParentType == UMLListViewItem::lvt_Datatype_Folder ||
                newParentType == UMLListViewItem::lvt_Logical_View ||
                newParentType == UMLListViewItem::lvt_Class ||
                newParentType == UMLListViewItem::lvt_Interface ||
                newParentType == UMLListViewItem::lvt_Package) {
            newItem = move->deepCopy(newParent);
            if (m_doc->loading())         // deletion is not safe while loading
                move->setVisible(false);  // (the <listview> XMI may be corrupted)
!               delete move;

which means that 'temp' the current list view item is destroyed.
