Exception initializing an RCP application... [message #519474]

Whenever I start up my RCP app I always get the below exception in the
HelpUIPlugin. It happens even before the first bit of my own code
(Activator-ctor) gets called, so I suspect it must be some problem with the
rcp core's initialization order.

Have I missed something, that causes this? Any ideas, how to fix or silence
this?

This is using Galileo...

It's possible that U call getWorkbench on start, but your plugin-haven't create the Workbench?

My plugin DOES create the workbench, but it is called only after that
exception already happened. You can see that by the output of misc.
println()'s at the very end of the stack trace: my plugin's Activator and
the Application constructor and start methods are called AFTER that
exception and thus didn't even have a chance to create the workbench at that
point.
