In RC2 I get this quite often exiting the runtime workbench. When it starts, I have the Ecore editor open, I click in the editor, and then I exit. I'm happy to screen share to debug it if that would help. !ENTRY org.eclipse.ui.workbench 4 2 2008-05-28 12:56:05.169 !MESSAGE Problems occurred when invoking code from plug-in:

I got this once in 3.4M7
Have you seen this in a build after 3.4.1? Looks like a duplicate of 202819. *** This bug has been marked as a duplicate of bug 202819 ***
I see this in our commercial product that is based on 3.4.2 final just recently released; should I reopen this bug or file a new one?
