[GTK] editing/selection/selection-modify-crash.html crashes when run in Xvfb

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Martin Robinson]

This is the crashing section of code:

AccessibilityObject* objectAndOffsetUnignored(AccessibilityObject* coreObject, int& offset, bool ignoreLinks)
{
    Node* endNode = static_cast<AccessibilityRenderObject*>(coreObject)->renderer()->node();
    int endOffset = coreObject->selection().end().computeOffsetInContainerNode();
    // Indication that something bogus has transpired.
    offset = -1;

    AccessibilityObject* realObject = coreObject;
    if (realObject->accessibilityIsIgnored())
        realObject = realObject->parentObjectUnignored();

    if (ignoreLinks && realObject->isLink()) <------- Guilty line
        realObject = realObject->parentObjectUnignored();

    [...]
}

The issue here is that parentObjectUnignored may return null, particularly in the case that the AccessibilityObject is a WebArea.
