Description kipu44 2014-05-08 14:55:10 UTC 
Application: umbrello (2.11.5)
KDE Platform Version: 4.11.5
Qt Version: 4.8.4
Operating System: Linux 3.11.0-20-generic x86_64
Distribution: Ubuntu 13.10

-- Information about the crash:
- What I was doing when the application crashed:

I added directed connection between classes, then I created point on the connection. After that I clicked on the point with right mouse button and choose 'Add point' option (should it be 'Remove point'?) and then Umbrello was suddenly closed.

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

>#7 0x000000000066722a in AssociationLine::isPoint (this=<optimized out>, index=index@entry=-1, point=..., delta=delta@entry=5) at ../../umbrello/widgets/associationline.cpp:386

The backtrace indicates a -1 a point index which is not been catched in the related code below.  

bool AssociationLine::isPoint(int index, const QPointF &point, unsigned short delta)
{
    int count = m_LineList.count();
    if (index >= count)
        return false;

!!!!    QGraphicsLineItem* line = m_LineList.at(index);
