commit e10ebb8bd33cf807e2edfa56c465b40f3237102e
Author: Ruben Vandamme <ruben@kmess.org>
Date:   Sun Jul 8 10:56:37 2012 +0200

    Fix crash in ContactListModel.
    
    * Individually delete every child instead of using qDeleteAll.
    * Crash only happens in combination with Qt 4.8.
    * See https://bugs.kde.org/show_bug.cgi?id=285951 for similar issue in Amarok.
    * See https://bugreports.qt-project.org/browse/QTBUG-22037 for Qt report.
    * Many thanks to Bob ("badjar" on kmess.org/board) for providing the fix.
