[kepler-dev] stack overflow problem in some kepler workflows

Hi Efrat,

    The stack overflow error that we get with the current head of CVS on 
your gravityToShp workflow has been obsessing me the last few days - why 
does it work with your saved version of Kepler and not with the head of CVS?

    It turns out that the problem occurs when you try to open the 
workflow - i.e. when the workflow moml is being read. I finally traced 
the problem not to any actor code but to the nice icons you added for 
the XSLT actor and the Browser Display actor! (Those icons do not appear 
if those actors are simply dragged to the screen, so I assume you used 
the 'Edit Custom Icon' command.) If you go into the moml and remove the 
properties that attach the custom icons, then the workflow will open 
with the newest CVS version of Kepler!!!  [The registrationModel 
workflow had a similar problem that is fixed by removing the custom icons.]

    Now, I don't know why the custom icons cause this problem (perhaps 
some changes in the moml parsing?), but at least we know better where to
