Description Atli Þór Jónsson 2010-03-29 04:44:23 UTC 
Application: umbrello (2.4.1)
KDE Platform Version: 4.4.1 (KDE 4.4.1)
Qt Version: 4.6.2
Operating System: Linux 2.6.32-17-generic i686
Distribution: Ubuntu lucid (development branch)

-- Information about the crash:
Was testing the code generation wizard using a simple test class. Had already generated a Java and PHP class (without closing the wizard), and when I tested C# it crashed.

Can't seem to reproduce it though and the back-trace doesn't tell me much. Perhaps it makes more sense to somebody more familiar with the code.

Note, I am running this on Gnome (Ubuntu 10.04 alpha), if that matters.

The crash does not seem to be reproducible.

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

Comment 1 Ralf Habacker 2015-08-18 17:15:41 UTC 
(In reply to Atli Þór Jónsson from comment #0)
> #6  UMLObject::getUMLPackage (this=0xbfdab538) at ../../../umbrello/umbrello/umlobject.cpp:606
This call is performed from 
QString CSharpWriter::makeLocalTypeName(UMLClassifierListItem *cl)
{
    UMLPackage *p = cl->getType()->getUmlPackage();

where  
UMLClassifier * UMLClassifierListItem::getType() const
is defined as
{
    return static_cast<UMLClassifier*>(m_pSecondary);
}
m_pSecondary could be zero, but isn't checked against in the statement

    UMLPackage *p = cl->getType()->getUmlPackage();
