Hi Roman,

I've just found a case which makes dash crash - this is when my test 
scope creates at least two duplicated results for given search request 
(same uri, title, icon... everything -  they need to be exactly the same 
to trigger the crash)
Can you check if same thing happens to your scope (may be a problem with 
the remote service you're using, not your scope)?

Cheers,
Pawel
