Comment 5 for bug 705267

I'm not sure I have the same problem as described above.
When I start Thunderbird using the message indicator (envelope icon), Thuderbird icon appears in the launcher. When I right-click on it and choose "keep in launcher" the icon stays there. But... After these, when I start Thunderbird through the message indicator again, the icon in the launcher is not active and it doesn't have an arrow, instead of that, an empty space appears on the bottom (there's no icon, just the space of it). After a right-click on that, the "keep in laucher" menu item seems to be checked. When I close the Thunderbird window after these steps, the empty space remains there. It disappears when I uncheck "keep in launcher" but the "keep in launcher" item of proper Thunderbird icon on the left bar gets unchecked as well automatically, although it stays in the launcher. When I hide it by checking then unckecking "keep in launcher" on it and I start Thunderbird using the message indicator, there is no Thunderbird icon or empty space any more on the launcher until I log out and back.
Skype has similar issues on my system since I updated yesterday evening. (I update daily.)
I'm using Oneiric right now, the oneiric-security and oneiric-updates repos (and a few PPAs but nothing that affects Unity AFAIK) and I don't use oneiric-proposed and -backports.
