I don't have time to figure the proper place for this report, but I just 
crashed the Simal demo server.

(1) uploaded Shudffl DOAP record - seems OK
(2) follow link to project browser
(3) clicked on Shuffl entry

Pop!: (details below)

The problem is repeatable in the current deployment by loading the root URI 
and 
repeating steps (2-3).

We'll need the DOAP file, or the URL for it so that we can reproduce this in 
debugging.

It looks like there is an null value for one of the items we are trying to 
display and 
we have not provided a default value.

I'm unable to reproduce this. I've tried it on my local test installation and 
on the 
public registry at http://registry.oss-watch.ac.uk

Apart from seeing a duplicate entry on the public registry, which is a 
different issue, 
I can find the Shuffl project and follow the link to the detail page.

Can anyone else reproduce it?

Marking invalid as we've been unable to reproduce and there has been no follow 
up since Mar 30 2010
