So there are few issues here. 

The first is a bug: when no category is selected there is an error we need to 
handle gracefully.

The second is how to pre-populate the database with categories. 

The third is how to add a new category to the database.

I've started a wiki page to document the workarounds for the last two issues at 
http://code.google.com/p/simal/wiki/AddingCategories

I've also added a couple of relevant issues: ISSUE369 and ISSUE368 to improve 
the situation
