Version: 1.5.71 (using KDE KDE 3.5.5) Installed from: Debian stable Packages OS: Linux When I change the name of the attribute pcDescriptionReader of the class PCDescriptionManagerFactory (see attached xmi file) the application crashes. There is also a KDE Crash Handler Backtrace file that I am attaching to this thread.
Created an attachment (id=21162) [details] class diagram that shows the described behaviour

SVN commit 688793 by okellogg: UMLObject::set{Name,Visibility}: Make virtual. UMLAttribute::attributeChanged(): New signal. UMLAttribute::set{Name,Visibility}: New. Reimplement methods from UMLObject in order to emit extra signal attributeChanged(). AssociationWidget::slotAttributeChanged(): New slot. Connects to UMLAttribute:: attributeChanged() when the AssociationWidget represents an UMLAttribute. The extra signal is necessary because the attribute name must already have been updated at the AssociationWidget by the time UMLObject::emitModified() is called else UMLView::createAutoAttributeAssociations() will think it needs to create a new attribute association.
