Saving website field on contribution form saves website with some integer value in it.

Following are the steps to replicate:
1)Create a profile for Organization(Name,Email and Website)
2)Configure that profile with one of the Contribution page.
3)Go for live contribution.
4)Add Organization name and email and leave Website field empty thus save Contribution.
5) An Organization (On Contact View page) would have been created with resp. name and email also showing up website with value as location type id.
(Same gets replicated even if we add website while contributing.But here it creates 2 websites, one with the actual value and other having location type id in it)
