Shotwell does not appear in Launcher as running nor in Alt-Tab sequence

[Zordid]

Right after upgrade to 12.04 LTS I notice that Shotwell, when started, does NOT appear in the launcher bar at all. I was surprised, cause I had just started it - right after it was up and running, its icon disappears in the bar.
Next time I started it, during the time the application started, I pinned Shotwell to the Unity launcher. But then you notice that while it is running, the icon is not decorated with a * to indicate a running application.

Further more: while it is running, it cannot be seen in the Alt-Tab sequence at all. It acts like not there, not running.

This happened directly after upgrading to 12.04 and was not there in 11.10!

Thank you for your bug report, does it fix itself after a session restart? Did you add it to the launcher in the same session? That seems similar to bug #772986 or bug #978392

[Zordid (zordid-gmx)]

Yes! That's it!
After I started a new session, it works - in the launcher as well as in the Alt-Tab sequence!

So it is the same issue and not associated with Shotwell, I suppose, but rather with pinning something to the launcher!

It might the same issue as bug #772986 and bug #978392... or not! In my case, on 12.04 freshly updated with Shotwell 0.12.3, the problem occurs only with Shotwell, as all other open/active apps icons appear in the launcher, event those that are not pinned.
