Hi guys,
I had tried another approach, I installed "Etoys-To-Go 5.0.1.app" on my Ubuntu, and interaction with Sugar work, as you can see in the following screenshot (http://ubuntuone.com/1Ax7rU0ikfZHH1n0NClzKe) , i can open Journal, but another kind or error raised:
Any idea ?
Etoys-To-Go is packaged with a VM that is compiled with Sugar support. When you run the script to start Etoys in Etoys-To-Go, it uses that VM rather than any other VM that you might have installed separately on your Ubuntu system. That explains why the startup now works.
The error that you are seeing now is something else. There is some sort of failure occuring during the image startup. Class SugarLauncher is trying to do something in its startUp method (that is a method that is sent to various registered classes as image start time). It looks like it is trying to retrieve some image from dbus having to do with its "ownerBuddy" (whatever that is, I don't know). It apparently expects to get some sort of XML data from dbus, and it's not getting it for some reason.
I'm completely guessing, but this might be just something to do with starting your Etoys-To-Go directly from the command line, when perhaps the SugarLauncher was expecting that it was started in some other way. Sorry I don't know any more about this, but look for some kind of problem related to Etoys not being able to get this initial information from dbus.

Dave,
I believe that squeakvm is compiled with Sugar support, because I can
run
Scratch and save projects on Journal, just in case, there is another
way to
know if squeakvm is compiled with Sugar support ?
If you run the VM executable directly with the -help option, it will print a list of available command line options. If the VM was compiled with Sugar support, the list of X11 options will include this:
-sugarBundleId <id> set window property _SUGAR_BUNDLE_ID to <id> -sugarActivityId <id> set window property _SUGAR_ACTIVITY_ID to <id>
If the VM does not have this, then it will not handle the command line option parsing as expected.
As far as I can tell, the Sugar support in the VM is used only to set some X11 window properties. I am not familiar with Sugar, so I do not know why this is important, but I would expect that the basic functioning of Etoys and Squeak would not be affected by this at all. So just for purposes of testing, you might want to try running Etoys with the following two parameters removed from the command line:
-sugarBundleId org.vpri.EtoysActivity -sugarActivityId > 24c67ec800d1d71723f959b56a213accf140e7bc
I expect that if you run it this way, then Etoys should start up normally and the "inverted dictionary" problem will be resolved. This will at least confirm the problem, then we can figure out what to do to fix it.

I paste bellow another test I had done:
As Scratch is working well with the interaction with Sugar, I copied
the
same parameters of Scratch starting script, and executed this from a terminal as:
sudo /usr/lib/squeak/4.4.7-2357/squeakvm -vm-display-X11 -swapbtn
-encoding
UTF-8 -vm-sound-ALSA -sugarBundleId org.vpri.EtoysActivity

Seem the script that start squeak is ok, right ?
Looks like it :-(. That implies theres a bug in the VM on ubuntu
:-(.
Might it be something to do with the vm-sound-pulse plugin
mis-parsing
the
command line? What happens if you start it with no sound (omit -vm-sound-pulse) ?
After reading this thread, I was initially confused by the command
line
options that are being passed to the VM:
-encoding UTF-8 -vm-display-x11 -xshm -sugarBundleId org.vpri.EtoysActivity -sugarActivityId c03be0a816bee1440f701b7d3b504b0968cb3274 -vm-sound-pulse
These are options that are parsed by the VM executable itself, as
opposed
to being passed to the Etoys image and evaluated there.
I took a look at the VM sources, and see that the -sugarBundleId and the -sugarActivityId parameters will be interpreted by the VM
executable
if and only if the VM was compiled with Sugar support:
# if defined(SUGAR) else if (!strcmp(arg, "-sugarBundleId")) sugarBundleId=
argv[1];
else if (!strcmp(arg, "-sugarActivityId")) sugarActivityId=
argv[1]; # endif
I expect that if the Etoys image is run from a script that specifies
those
two VM parameters, and if the VM was not compiled without Sugar
support,
then the command line parameters are probably going to get out of
whack.
The dictionary that got turned inside out is probably a side effect
of
this.
So my guess is that the script is trying to run a VM for Etoys in
the
Sugar environment, but the VM that is being run by that script was
not
compiled with Sugar support enabled.
