For pharo2 I used seaside one click experience app downloaded directly and 
with no more modifications to the stock image.
For pharo3, I downloaded pharo3 and installed seaside 3.1 via Gofer.

So this, in theory, is reproducible with stock images without any further 
modification to image.

I want to point out that also, debugger is not raised in any of the two 
versions, only little error message in browser when something happens inside 
seaside, for example, a message not understood. That is really important, 
because it can be very hard to find with only the error title.
