Steps to repro-

1. Create a new plug-in project outside workspace. That is, uncheck default location on the new plugin wizard and provide a location which is outside the workspace.

2. The manifest editor will open. Go to ext. pt. page. Click Add and create a new ext. pt. Let the open schema editor check be selected.

SWTException is thrown as editor open.

Reproducible : Always

I've seen what appears to be the same exception trace thrown in Eclipse 3.6 (20100617-1415) when using a Wizard (in a WizardDialog) where I call "getContainer().run(true, true, runnable)" multiple times with different runnables.  Sometimes after the 2nd runnable is run in this way, the exception will be thrown; other times it completes normally.

I think it's important to note that the an AccumulatingProgressMonitor is being used (from the stack trace).  I suspect that when the monitor does an asyncExec() to update the UI (e.g. in setTaskName()), it's possible that the WizardDialog gets closed before the runnable runs?
