Figure.validate() crashes [message #218027]

Sometimes I get this call-stack after disposing the canvas containing my figure; anyone know why? is
it a Figure bug, or is there some action I should be taking?

thanks,
Paul

When the canvas is disposed, the updatemanager is supposed to be disposed
too. I thought that this typically happens for free, but maybe not in all
cases.

Your not alone. I started getting these lately as well. Not sure if its
the same stack trace as I haven't investigated. But I am getting the
exception.

Note that the above method returns without doing anything if the manager has
been disposed. You should always dispose the manager when the canvas is
disposed, since painting and layout occur asynchronously.

Only manager I created is a DeferredTreeContentManager but it does not
dispose. I didnt make any changes to the figure layer. Im just using a
TreeViewer. Its not GEF related. Again, I'm not sure where the exception
is being thrown so it could be something different.

Weird -- I did not create that object and do not have a handle to it (that I know of); when and how
should I dispose it?

So I have entered a new bug, https://bugs.eclipse.org/bugs/show_bug.cgi?id=148412, which seems very
similar to the fixed bug https://bugs.eclipse.org/bugs/show_bug.cgi?id=24716 ...
