I don't really consider styling issues as bugs. The admin toolbar is strictly a skinning element, it is not a required way to show admin links. If it doesn't work well for the main language of your site then other approaches can be used for admin links in your skin. I designed it to make sure it works at 1024x768 using English, but of course I can't promise it works with longer text.
you could try setting smaller fonts or removing the icons by css if you prefer the toolbar presentation, or you can come up with some other creative way to show those links.
