Major issue of "Page Not Found"

I have found a major issue of "Page Not Found"...

I created a page view
I added a field of "Delete Link"
I enabled pager for this View.
Then i saved view.

When i open view and go to second page through pager of view.
Then i clicked on "Delete" link and goto delete node page,
As you know here is "Delete" button and "Cancel" link.
When i clicked on this "Cancel" link, "Page Not Found" is opening.
It is a critical issue. Please help me to solve this issue.
