Ubuntu Software Center Unity launcher integration is not working

[Gary Lasker]

software-center version 5.1.8
unity version 5.2.0-0ubuntu2
The Precise Pangolin

Please refer to bug 761851 for details on this feature and its development. With the rollout of unity 5.2 and software-center 5.1.8 just after alpha 2, this feature should, in theory, be landed. However, I am not seeing any application icon appearing at all in the Launcher when doing an installation (note that this feature applies only to launchable applications with desktop files).

To reproduce:
1. Launch the Ubuntu Software Center.
2. Make sure that the Software Center's "View"->"New Applications in Launcher" checkbox menu item is checked.
3. Navigate to the Games section. Choose any fun-looking game and install it.

What should happen:
4. The icon for the game should appear in the Unity launcher immediately at the start of the install, and it should begin to fill its progress bar as the installation proceeds. At the end of this process, the launcher icon should be fully functional.

What does happen:
4. No icon appears in the Unity launcher at all.

Note that I have verified that I am sending the dbus signal from USC at the start of the install.

Thanks!

Bilal, I assigned this to you initially, but feel free to reassign as needed. And thanks!!

Status changed to 'Confirmed' because the bug affects multiple users.

The branch has been lying around for quite a while, any Unity dev around to merge it? It's just a one-line change :)

Also, for the remaining part of the SC integration, I've completed it, just ironing out some kinks and by tomorrow I'll propose it for merge too :)

What if you try to install a program, and don't give the password, thus stopping the installation? Result, icon remains on launcher, but program is not installed...this is bad, the icon should disappear.

[eden6000 (eden6000)]

Also, it seems that if you install a program, then remove it, its icon still remains in the laucher.

I don't agree with this change of status, the two issues on comment #5 and #6 are still present on my machine...do I have to file a new bug for them?

[Didier Roche-Tolomelli (didrocks)]

eden6000: those are already in 2 other bug reports that are filed against unity.

[eden6000 (eden6000)]

thanks Didier, I didn't see them...

I'm experiencing something a bit weird. As soon as I start installing something from the software center, a '?' icon appears on the launcher - but there's no progress bar on it. Also, it won't go away when cancelling the download/install or removing the application. In addition, after the application installs the icon stays as a '?'
