Hello Robert

There are a couple of installation problems with your Qt there. First of all, 
the Sqlite driver seems to be missing. We don't use it in Subsurface (AFAIK), 
but I've never seen a Qt installation without it. Its absence is probably a 
symptom of a larger problem.

How was that Qt built and installed? Did you use MacPorts? Or was it the 
official Qt 4.8 from qt-project.org?

You have D-Bus installed and configured for dynamic session support, but the 
support was not loaded into launchd on your Mac. Another installation problem.

Looks like a null-pointer dereference.

The code in question is:
	if (!parent.isValid())
		parentItem = rootItem;
	else
		parentItem = static_cast<TreeItemDT*>(parent.internalPointer());

	int amount = parentItem->children.count();
(the last line is 1049)
