The two test classes are not from me and reproduce not my error. I replied on this topic, because it is a similar error and it occures in the same region of code like the original.
As I mentioned in my post, I have no small test case. I have 2 UI-classes that are very complex and huge. In one, the error occures and in the second not. In the not working class, I use also the griddata.exlude command, like in the original post, but this seems not be the cause of the error. Both UI's uses similar widgets, Composite, Sash-Form, Text, Label, NatTable, CCombo... mostly with GridLayout.
Eclipse-Version is 4.3 Kepler (3.9.0.v20130326-1255) and WB-Version is 1.6.0.r43x201305212024[201307171427]
I will try to build a test-case.

This is my first post here, I wouldn't like to interrupt discussion but I had the same problem with I was able to fix, perhaps it will help you to find the real problem.
Part of my exception log:
java.lang.ArrayIndexOutOfBoundsException: 2
at org.eclipse.wb.internal.swt.model.layout.grid.GridLayoutInfo.fixEmptyColumns(GridLayoutInfo.java:204)
at org.eclipse.wb.internal.swt.model.layout.grid.GridLayoutInfo.refresh_afterCreate(GridLayoutInfo.java:169)
Solution was to change 3->2, which is 'horizontalSpan':
myGrid.setLayoutData(new GridData(SWT.FILL, SWT.TOP, true, false, 3->2, 1));
Crash happened for parent controls/classes, not for the control/class where the 'myGrid' was implemented. Child control/class works fine, it is visualized correctly by WindowBuilder Design mode.
P.S. Sorry for my bad English.
