We get a couple of exception reported like these:

java.lang.NullPointerException
	at org.eclipse.swt.widgets.Control.internal_new_GC(Control.java:2134)
	at org.eclipse.swt.graphics.GC.<init>(GC.java:171)
	at org.eclipse.swt.graphics.GC.<init>(GC.java:134)
	at org.eclipse.swt.custom.CLabel.getTotalSize(CLabel.java:260)

Maybe this is some variant of the "no more handles" problem.
