OK. Searching for いかがわっしい now gets:
 いかがわっしい (etc.) See: 如何わしい

Yes, I can see some unintended consequences of putting in pseudo-entries for patterns like いかがわっしい. I'll handle it a different way which will simply point to the base entry. SHould take a day or so to spread.

Seeing as there's a similar ghost entry for したっしい, I think this is something Jim has automated to deal with things like しょっぼい, an 
emphatic version of しょぼい? (rejected entry suggestion 2845566) It's a little unfortunate however if these actually appear in searches for 
"suspicious" etc. on WWWJDIC. I think it'd be fine to scrap this entirely, but the ideal might be if these forms could be recognized if you 
search for them but just display the いかがわしい, しょぼい etc. entries instead.

Hi, there seems to be a phantom entry in WWWJDIC:

いかがわしい 《如何わしい》 (adj-i) (1) (uk) suspicious; dubious; unreliable; (2) (uk) indecent; unseemly [Links]
いかがわっしい (See 如何わしい) (adj-i) (1) (uk) suspicious; dubious; unreliable; (2) (uk) indecent; unseemly [Links]

If you try the edit database links on the いかがわっしい entry, they lead to an error page
