When the start center is closed, Math has a wrong translation in the file menu, the mnemonic is visible. Instead of "Datei | Formel" it is "Datei | F~ormel". Only visible when start center is closed and thus the reduced menu is visible. Applies to RC2. Maybe checking for Windows quickstarter entry makes sense, too.
Florian: Can you please create a screenshot? I am not sure I am getting where exactly it is wrong (and I don't have the .de version at hand to see myself) - it'll help to locate if it is in the translation, or in the code.

Attached ;) I'd guess it's in the translation, but I'm no expert.
It must be STR_DESCRIPTION_FACTORY_MATH in svtools/source/misc/imagemgr.src. English string did not have ~ while the German string did. Fixed in l10n/source/de/localize.sdf in libreoffice-3-3 branch.
