Cannot drag applications from dash to desktop

i don't know what you mean by applications applet, could you be a little bit more descriptive, or provide a screenshot or something?

Step1(screenshot)

Step2(screenshot)

Step3(screenshot)

In other words, there is no easy way to create application shortcuts on the desktop!

Same problem here.

it also hapen with me error is " the specified location is not support"

your report is incomplete go to terminal and write
apport-collect 756614

use this to complete ur report
apport-collect 756614

Same problem here as well. Get a 'There was an error getting information about "/".' message when I try to drag and drop an Icon from the launcher to the desktop.

This doesn't appear to be fixed in unity (3d), typical error - attached

Confirmed, this bug is not fiexed in unity 3d.

Have you been updating everything? App lens, libunity, etc?

Hmm, - was fully updated as of 9 hrs ago (main server on a beta 2 install.
After a cold boot this morning it now works as intended..

Just to note - if grabbing from 'Most frequently used' it will produce the error, from 'installed' is fine

Partially fixed in unity 4.20.0-ubuntu2

Doesn't work for "Most Frequently Used" section.

I'm changing the status so this generates proper attention.

Ok, looks like I can't change status once it's marked as released. New bug report: #864016
