Description Tex Morgan 2012-02-20 05:37:15 UTC

Application: umbrello (2.7.4)
KDE Platform Version: 4.7.4 (4.7.4)
Qt Version: 4.7.4
Operating System: Linux 3.0.0-16-generic x86_64
Distribution: Ubuntu 11.10

-- Information about the crash:
- What I was doing when the application crashed:
I was changing the background using Fill Color of a note in a diagram I had made.  The program popped up the color change menu, but then crashed when I selected a color.  I had already done this once successfully, but am unsure as to what went wrong the second time.

-- Backtrace:
Application: Umbrello UML Modeller (umbrello), signal: Segmentation fault

Comment 1 Ralf Habacker 2015-03-13 20:06:00 UTC

Could not be reproduced with 2.10.5. 

From the backtrace 

#6 0x0000000000692fb6 in UMLWidget::slotMenuSelection (this=0x2f98680, action=<optimized out>) at ../../../umbrello/umbrello/widgets/umlwidget.cpp:320
the related code fragment is shown below: 

    case ListPopupMenu::mt_Fill_Color:
        widget = m_pView->getFirstMultiSelectedWidget();
        if (widget) {
            newColour = widget->getFillColour();
        }
        if (KColorDialog::getColor(newColour)) {
            m_pView->selectionSetFillColor(newColour);
            m_pDoc->setModified(true);
        }
        break;

The bug report says:

> The program popped up the color change menu, but then crashed when I selected a color. 

which happens in KColorDialog:

        if (KColorDialog::getColor(newColour)) {

The mentioned back trace frame number 
> #6 0x0000000000692fb6 in UMLWidget::slotMenuSelection 
which is not the top of the frames indicates also that this crash happens in basic kde libraries.
