OK. WWWJDIC now block conjugations of verbs ending in られる and させる.

Thanks for pointing this out. I need some way of blocking WWWJDIC's conjugation table generator for cases like this. I'll leave this open to remind me.

If you go to the ichidan verb list to see all the types you can see for 
example that there is たべられられる available! This wrong...many verbs 
have false types like this..

Fair enough. I also need to include the potential form, in case a beginner comes across the entry.

not sure it needs to be both v1 and adj-pn unless the senses are split.  verbs normally can be used prenominally similary to an "adjective".

so i think the PoS should either be [v1,vi] or else split into two senses by PoS: [v1,vi] and [adj-pn]
