--- Comment #2 from Oliver Kellogg <okellogg at users.sourceforge.net> ---
Confirm on git master.
Analysis:
AssociationGeneralPage::updateObject() accesses  m_pStereoChkB->isChecked()
without prior check of m_pStereoChkB against NULL.
However, m_pStereoChkB is only non NULL for associations which have an
underlying UML object, see
umbrello/dialogs/pages/associationgeneralpage.cpp:113 ff.:
    if (umlAssoc) {
        // stereotype checkbox
        m_pStereoChkB = new QCheckBox(i18n("Stereotype"), nameAndTypeGB);
        [...]
    }
