I'm running Ubuntu 9.04 too. When I installed the SDK I did have the layout set as US International. I wonder if that is the issue. Does the scratchbox take on the keyboard layout used during the install? I notice that I still have to hit a space after pressing the " key for it to be entered, when using the scratchbox. I still don't see why the US International layout would be a problem though. But, I am willing to change the layout manually in scratchbox if that will fix this. I guess I'll have to dig around for a way to do this.
