Flickering and unknown icons in the window bar

[couf]

SoaS build: 20090503...

After starting a couple of programs, we notice that some of the programs started leave the flickering start icon in the window list. The window of the program is indicated with a dark circle in the bar.

Screenshots attached: the first browse icon and the terminal icon in the screenshot are flickering. The actual program are accessible with the dark circles in the application bar.

Reproducing this is pretty hard. It mostly happens when starting the bigger programs (like browse or etoys) followed by opening some others.

When it happens, I do see the following in the shell.log:

As an extra effect to be considered with this bug: when closing the program's the circle-icons still exist: see screenshot 3.

For these 4 month many fixes were commited to sugar that can affect this issue, is it still reproducible in at least 0.85.7 sucrose?

Milestone soas_fossvt deleted

|TestCase|
1) on XO-1.5 (more chances to reproduce on restricted, like XO, machines)
2) switch to F3 (list view)
3) launch new activity
4) as fast as possible go to 2

sucrose-0.88 patch, needs to de midified to apply to the trunk

[alsroot]

Attached patch call wm.set_bundle_id() for launcher window (thus code that monitors created windows will work properly), also it prevents re-creating launcher in ShellModel.notify_launch() (this code might be different in the trunk).
