[Seaside] Seaside 2.8a1-lr.518 - VW7.6 27 - weird thing happening

[Claus Kick]

Hello everyone,

I am experimenting with Seaside 2.8 on VisualWorks 7.6.
After implementing some components, I figured I should get more 
accustomed with VisualWorks itself first, so I wrote a few classes 
(nothing in the Seaside class hierarchy).
Now this is mostly done, so I wanted to go back to working on the 
Seaside project.

But strangely enough, my app does not work anymore. Ok, perhaps I made a 
mistake with it, so I tried to have a look at its configuration.

Turns out I receive this stack trace when I click on "edit" for that app :

Possible Causes

     * you sent a message this type of object doesn't understand

       value
           a Seaside.WAValueHolder contents: a Seaside.WAAnswerHandler

    5.

       thisContext
           Seaside.WASnapshot(IdentityDictionary)>>keysAndValuesDo:
       self
           Seaside.WASnapshot (a Seaside.WAValueHolder contents: a 
Seaside.WAAnswerHandler->a Seaside.WAValueHolder contents: a 
Seaside.WAAnswerHandler a Seaside.WAValueHolder contents: a 
Seaside.WAWalkback->a Seaside.WAValueHolder contents: a 
Seaside.WAWalkback )...etc...
       aBlock
           BlockClosure [] in Seaside.WASnapshot>>restore
       index
           2
       key
           a Seaside.WAValueHolder contents: a Seaside.WAAnswerHandler

Restarting Seaside did not help.
Trying to remove the Application Configuration also returns a walkback, 
as does trying to access the tests or the examples.

What can I do now?
