App Indicator not showing apps launched with Wine

[Tarek]

System: Intel® Core™ i3-2120 CPU @ 3.30GHz × 4, 3,8 GiB RAM
OS: Ubuntu 13.04 64 bits
Unity: 7.0.0daily13.04.18~13.04-0ubuntu1
Wine: 1.4.1-0ubuntu5

Given that I launch an app with wine that has a systray icon
When that app opens
Then I should see the systray icon displayed in the App Indicator
But the icon is not displayed
And I can only see the icon when I open the Workspace switcher (Alt+s)
Or while switching workspaces (ctrl+alt+arrow)

Since Wine nor Unity crash, I couldn't find any log or useful debug info on the problem.

It used to work in 12.10, so I think the problem is related to the recent removal of system tray support (http://www.omgubuntu.co.uk/2013/02/raring-retires-system-tray-whitelist). Yet, as I understand, Wine apps are whitelisted. Maybe the problem is that Unity is not recognizing the app as being launched by Wine?

EDIT: tested with Pidgin to make sure the behaviour wasn't app specific. The bug was reproduced.

Status changed to 'Confirmed' because the bug affects multiple users.

I have the very same bug, but it started to occur since last week. Steam was fine with Wine, but now I can't see the tray icon. Also I had trouble installing .NET Framework because the installer uses a tray icon too.

Forgot to mention I'm using 13.10, so it might be something else than a tray support related problem.

What's the wine that you are using to reproduce the bug?
