Description Wassim Melhem

I got several of these NPEs as I was debugging my runtime Eclipse app.

Each NPE was accompanied with an error dialog.

i have also this.
And i looks when i have this i also have this exception in the log: (this happens before the debug nullpointer)

java.lang.NullPointerException at org.eclipse.debug.internal.ui.actions.CopyToClipboardActionDelegate.initialize(CopyToClipboardActionDelegate.java:43)
bugs: 131884 133317

Version: 3.2.0
