Google +1 button not opening "share this" bubble

Question

I'm having some strange behavior with google plusone button.

When a user clicks +1 button, I expect the "share this" bubble to open, but it wasn't opening, so I stripped everything from my page, removed all unnecessary html/css/js and get this page with only google+1 button

works fine as expected, then I add a jpg to the code

<img height="250" width="650" alt="" src="http://www.benimgibi.net/wp-content/uploads/2012/03/gj1u0tfwyjmtwfv7.jpg" />    

and it wont work, you can see here: http://demo.benimgibi.net/dikkat-ne-kadar-renk-o-kadar-vitamin/?v=2

What is even more strange is, if I change the width of the image to a very small number, say 50, it works again.

you can see that version here: http://demo.benimgibi.net/dikkat-ne-kadar-renk-o-kadar-vitamin/?v=3

NOTE: +1 works fine in all cases, but Share bubble doesn open at version 2. What I mean with "Share bubble" is

Answer 1

For me it is opening in all the cases. Yeah but for version-2 it is taking few extra seconds to respond.

But anyways,

Your picture cannot be the reason behind it.

So keep that out of mind, there may be other reasons for late response.
