umbrello recurses into UMLObject::getFullyQualifiedName() until a stack overflow occurs. 

The related code snippet is listed below see !!!!

QString UMLObject::getFullyQualifiedName(const QString& separator,
        bool includeRoot /* = false */) const
{
    QString fqn;
    if (m_pUMLPackage) {
        bool skipPackage = false;
        if (!includeRoot) {
            UMLDoc *umldoc = UMLApp::app()->getDocument();
            if (umldoc->rootFolderType(m_pUMLPackage) != Uml::N_MODELTYPES ||
                    m_pUMLPackage == umldoc->getDatatypeFolder())
                skipPackage = true;
        }
        if (!skipPackage) {
            QString tempSeparator = separator;
            if (tempSeparator.isEmpty())
                tempSeparator = UMLApp::app()->activeLanguageScopeSeparator();
!!!!            fqn = m_pUMLPackage->getFullyQualifiedName(tempSeparator, includeRoot);
            fqn.append(tempSeparator);
        }
    }
    fqn.append(m_Name);
    return fqn;
}


The problem is that there is no exit condition. From my point of view a propper exit conditions would be to change the line 

    if (m_pUMLPackage) {

into 

    if (m_pUMLPackage && m_pUMLPackage != this) {
