Spread and Expand are translated the same way in german (de.po)
The combobox "Layout style" for GtkButtonBox has two entries "Spread" and "Expand" which are translated both with "Ausdehnen".
This makes it impossible to select the correct option:
I have no really good idea, but a suggestion:
- Spread - ausbreiten
- Expand - ausdehnen (or just "expandieren"?)
