Description Joris Steyn 2013-12-29 10:54:24 UTC

Umbrello crashes when adding a widget to a diagram. This happens only to widgets of a specific type. The crash can be reproduced by adding an artifact or interface to a component diagram. Some widgets on deployment diagrams (and probably more, class diagram widgets seem fine) result in the same crash.

Problem exists in master (see bisect below) - 4.11/4.12 are fine.

Reproducible: Always

Steps to Reproduce:
1. Add component diagram
2. Add an artifact

    Refactor WidgetBase derived classes to use setSelected() and
    isSelected() from QGraphicsItem instead of self provided
    members/methods.
