[Bug 36052] Crash moving icons between monitors

[Don Scorgie]

Public bug reported:
https://launchpad.net/malone/bugs/36052

Affects: nautilus (Ubuntu)
       Severity: Normal
       Priority: (none set)
         Status: Unconfirmed

Description:
Using a dual monitor, non-xinerama setup.  I can post my xorg.conf if
needed.

1. Create an object (a folder) on one screen
2. Drag object across to second monitor
3. Watch nautilus crash-n-burn

Default theme.  This works as expected in a default jhbuild Gnome 2.14
session (i.e. the icon is moved across monitors).  This is using Dapper.

Stack trace with nautilus-dbg installed.
