image indicating unknown string
The image, shows underlined in red a string not translated, or better, a shortcut undefined.
I think it should be Ctrl+Shift+Y, instead of "Redo".
Actually the issue is also in Writer. A module common to all?
Same problem in French: instead of "Redo" as in your version I have the word "Répéter" which means redo. But there we should have a shortcut not a word.
Found in LibreOffice 3.4.1 rc1 for Ubuntu x86_64 with langpack FR.
What is even more interesting: if I switch the UI in English the word is even "Encore" in French. All other menu items being in English of course.
So, for me, the problem is not a translation bug but, probably, an uninitialized variable bug.

Accelerator key of the .uno:Repeat command is defined as Y_SHIFT_MOD1, later it is redefined as REPEAT for most modules (officecfg\registry\data\org\openoffice\Office\Accelerators.xcu). It is possible to change REPEAT to Y_SHIFT_MOD1, this solves the issue. But I think it would only work-around the real bug somewhere else.
Vanished in LibreOffice 3.4.2, Build 203
