This is a follow-up from bug 354243. From bug 354243, comment 6: " The label should overflow the button. The crop attribute should be used to crop the label, but that doesn't seem to work :( " I'll attach a testcase. The testcase works in Mozilla1.7, so I'm marking this a regression.

Button text cropping does not work anymore on linux too. testcase: http://www.mozilla.org/projects/xul/tests/buttons.xul

This bug results from Bug 414711 (In a cropped label, text overruns label width (text size computed wrong?)). You can make the cropping work for both bugs by setting flex="1" for the label. It only works for flex-values bigger than 1. I tested it, by adding flex to the label-child of the xbl-binding of the button and the buttons where correctly cropped.
