Debugger tests

[Vladimir Prus]

While running debugger tests after some changes, I see this:

	FAIL!  : GDBDebugger::GdbTest::testStackFetchMore() Compared values are not the same
	Actual (stackModel->columnCount(QModelIndex())): 3
	Expected (1): 1
	Loc: [/home/ghost/Work/KDevelop4/src/kdevelop/debuggers/gdb/unittests/gdbtest.cpp(654)]

Yet, looking at framestackmodel.cpp, I see:

	int FrameStackModel::columnCount(const QModelIndex& parent) const
	{
	    Q_UNUSED(parent);
	    return 3;
	}

Is the test itself in error, or am I missing something?
