A problem like that would have to be solved by CSS. It isn't something I plan to solve per language. The trick would be to make the boxes large enough to fit the text, it may require larger images as well.
We provide those icons for convenience but one could easily just remove this from style.config:
<file cssvpath="/Data/style/adminmenu/style.css" imagebasevpath="/Data/style/adminmenu/">none</file>
Then it will just be a simple list that should work fine with any text. Or you could add your own css and style it any way you like.
I do not consider CSS/style issues as bugs, so I have moved this thread to the design forum from the bugs forum where you posted it originally.
