nautilus/files doesn't show up in the launcher when unpinned

[Gustav Ekner]

[Impact]

When nautilus is unpinned, it doesn't show up in the launcher. When it's pinned, you can see the open windows with arrows on the side as usual, and switch between windows if there are several of them. But when I unpin it, it will disappear entirely. Sometimes when I open it, it will display for one second and then disappear.

[Test case]

 - Unpin nautilus from launcher (via quicklist or trashing it)
 - launch "Files" from dash
 - Nautilus icon should stay in the launcher until the file manager is opened

[Regresion potential]

Nautilus icon might stay there also if not pineed

Thank you for taking the time to report this bug and helping to make Ubuntu better. Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures.

At a minimum, we need:
1. The specific steps or actions you took that caused you to encounter the problem.
2. The behavior you expected.
3. The behavior you actually encountered (in as much detail as possible).
Thanks!

[Sebastien Bacher (seb128)]

Unpinning and going to the dash and typing "nautilus" and click on the icon makes it show in the launcher for me, you are going to describe what you do exactly better. Note that if you open/close it sometime it goes missing which is likely bug #1572348

[Sebastien Bacher (seb128)]

Hum, in fact the icon is added there but then removed a bit after that, is that the same issue you see?

[Gustav Ekner (gustav-ekner)]

yes

[Gustav Ekner (gustav-ekner)]

A more exact way to reproduce: ("Files" will be referred to as nautilus)

-- Start by having nautilus pinned and closed --

* Open nautilus
* Unpin it (it will still display, as excepted)
* Close nautilus (now it won't display, as excepted)
* Open nautilus via the dash
* Now it will display for approximately one second, then disappear (it shouldn't disappear)

[Gustav Ekner (gustav-ekner)]

I have tested this on another machine with Ubuntu 16.04 now, and I can reproduce it with these steps there as well.
