Comment 6 for bug 925421

@Thomas: is that still an issue with this SRU:
https://launchpad.net/ubuntu/+source/unity/5.12-0ubuntu1.1

it seems it the bug got closed on the basis that it's similar to some of the issues fixed in that SRU:

"- App icon on the Unity Launcher lost track of running
      instance (LP: #772063)
    - No launcher icon or Alt+Tab entry for Gimp windows (LP: #995916)
    - Locked smuxi launcher icon does not indicate smuxi running
      status (LP: #999820)"

I didn't notice the issue described here recently but if it's still happening we will need to reopen and I will ping the unity team to look into details to it, do you use the same steps that the ones described there to reproduce the bug?
