Follow-up Comment #9, bug #54920 (project octave):

Rik:  Yes, I think you are correct.  It doesn't happen for fltk because the
toolbar action for autoscale is executed as a callback to the Octave
interpreter.  You can see that this approach also works for the qt toolkit by
using the autoscale item in the tools menu instead of the autoscale button.

I can fix this by wrapping the actions in try/catch blocks.  There are
probably other places where these problems could happen and we could attempt
handle them all individually.  But this seems like a difficult thing to do
since there are probably many actions that call functions from the interpreter
could potentially result in an error.

Also, should the be implemented using an Octave ui object as they are with the
fltk plotting window?
