Stange error with Chrome hosted mode

Hi to all
There was and old topic on that error, but i can't find it anymore...
i found it on google but the page doesn't exist either in the google
cache.

I'm tryng to use the hosted mode in chrome too... but i can't.

I can use it on IE and Firefox (in this day i can't with firefox,
because the plugin in is not compatible with the last firefox
updgrade).
My project in "normal" mode works also in Chrome, but in hosted mode i
get this error

onModuleLoad() threw an exception
Exception while loading module com.fdlservizi.sse.client.HelpDeskGWT.
See Development Mode for details.

I'm using GWT + GWT-EXT and the java code and the point of the failure
is:

VerticalPanel vp = new VerticalPanel();
vp.setHorizontalAlignment(HorizontalPanel.ALIGN_CENTER);
vp.setVerticalAlignment(HorizontalPanel.ALIGN_MIDDLE);
vp.add(logoWelcome);
Panel pannelloVuoto = new Panel();
pannelloVuoto.setHeight(150);
vp.add(pannelloVuoto);
logoSA = new Image();
logoSA.setPixelSize(300, 90);
vp.add(logoSA);
pannelloInterno.add(vp);
panelPrincipale.add(pannelloInterno);

(the line 107 is: vp.add(logoSA);)
so nothing special

Some one can help me?
