[Zope] Cannot add tutorial: connection error

[Ulrich Rueth]

Hi all,
I'm new to Zope and tried to add the tutorial to my workspace. After 
entering the ID and pressing "Add", I got this Mozilla (I'm running Zope 
under SuSE Linux/Mozilla0.9.9) error message box telling me

"The connection was refused when attempting to contact localhost:8080"

Additionally, I got the Python error message in the window where I 
started Zope (unfortunately in German, I'll try to translate it)

python: Python/ceval.c:687: eval_code2: Zusicherung »(stack_pointer - 
f->f_valuestack) <= f->f_stacksize« nicht erfüllt.

which is in English something like

python: Python/ceval.c:687: eval_code2: Criterium »(stack_pointer - 
f->f_valuestack) <= f->f_stacksize« not met.

Can anybody give me a hand? Your help is appreciated!

Regards,
Ulrich
