I found the offending part in the ZPT that caused the abovementioned 
assertion.

I have a pagetemplate that uses master macro from main template, then 
the main template includes the other template (portlet) that eposes slot 
to be optionally overriden in template using it (main in my case).

test.pt
    <... metal:use-macro=...>
        main.pt metal:define-macro
            master
                <... metal:use-macro=...>
                    portlet.pt metal:define-macro
                        portlet
 >                           <... define-slot=...>
                               /default slot content/

As soon as I remove the level marked with > my page renders fine with no 
exception. If I want to expose flexibility of my portlet with that slot, 
the whole construct breaks with exception :(

Any hints appreciated,

Regards,
