On selecting any fact with integer value from auto-search under New discovery rule form, raises 500 ISE

Description of problem:
While defining the discovery rule, in search box I choose the auto-search and defined "cpu_count = 1" 

As soon as I defined "cpu_count = 1" in serach, UI raises 500 ISE in firebug and poduction.log thrown:

--
