Applications that remain running in notification area get relaunched

Hi Newfie

Thank you for taking the time to report this bug and helping to make Ubuntu better.

I can confirm that when using the package unity2d on Ubuntu 10.10 using the steps provided by Newfie that I can reproduce the bug. Therefore I have set this bug to confirmed.

How I reproduced:
Opened up Opera by clicking on icon in Unity.
Minimised Opera to the notification area by right-hand clicking on the Opera Icon in the notification are and selecting 'Hide Opera'.
*I noticed that the arrow in unity disappeared at this point, suggesting that Opera had been closed.
I then clicked on the Opera icon in Unity and Opera appeared with a new tab open.
Instead I would have expected Opera to be unminimised as the application is already running.

This only happens to applications that use the old notification area rather than the new area which has for example the sound applet, because this behaviour cannot be reproduced with application that use applets such as Rhythmbox.

Also, this happens because XChat allows to open more than one instance of itself. This behaviour is often prevented by the application itself, for example Totem.

Bug #667050 seems to be a specific instance of this bug.

set to medium, as skype was the only application from default whitelist that inhibited this issue, now since skype is using an indicator the bug only affects the manually whitelisted apps only.

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.

Hm... Sorry, my issue is Bug #756639.

I mean Bug #943877. :)
