Add a gtext element:
bodyText = bodyBackground.addTextObject("This is some text", "Arial", 20, "Black", 0, 0);
Then change the text to something shorter:
bodyText.value = "Text";
And you end up with "Text" streched to fit the original width of "This is some text"! Surely, it should recalculate <gtext>.width to the width of the new value

Changing <gtext>.value doesn't update <gtext>.width

bodyText.value = "Text";
bodyText.width = 0;

If you want the Gadget (Polaroid) that sparked off all the issues I've recently reported, head here. In the end I opted to remove all the g:background objects and recreate them.
What was supposed to be a one hour gadget, turned into two days of trying to work around all the bugs I found in Sidebar. I think I found six in the end!
