Comment 6 for bug 149468

I found zenity didn't crashed on other distribution based gtk+ 2.12(Rawhide, Gentoo with gnome-experimental layout).

Just disappeared Desktop icon in bookmark when release mouse button.

So, I propose that reassign bug to nautilus in gnome bugzilla, and change priority to enhanced. cause nautilus might have same behavier with gtkfilechooser.

And assertion is happened only ubuntu. It need some more tracking.
