German hyphenation ist not working in calc 3.4 rc1 20.5.2011.
calc says that the hyphenation is set for the not worken region.
If you transfer an calc sheet created with 3.4 rc1 into writer 3.3.2 and open it and click into the sheet under 3.3.2 the missing hyphenation is made.
I can confirm that hyphenation is broken with the bundled German (de-DE) dictionary, version 2011-05-05;
tested [on WinXP 32b] with LibO 3.4 Beta5, LibO 3.4 RC1, LibO 3.4 nightly v2011-05-20 (the same bug with OOo 3.4 Beta1 and OOo-dev DEV300m106).
Hyphenation works well with the also tested languages English(USA) and French (France).
How to reproduce (Writer):
[English, French and German (DE) dictionaries installed/enabled.]
1. Menu Tools > Options > Language Settings > Writing Aids > Options >
[ ] Hyphenate without inquiry [disabled]
2. Open the attached text document ('hyphenation_en_fr_de.odt').
3.1 Select paragraph  [Text body, English (USA)]
3.2 Menu Tools > Language > Hyphenation...
3.3 Pop-up window with dialog 'Hyphenation (English (USA))' [psy=cho-analysis.]
OK - as expected
4.1 Select paragraph  [Text body, French (France)]
4.2 Menu Tools > Language > Hyphenation...
4.3 Pop-up window with dialog 'Hyphenation (French (France))' [Au-triche]
OK - as expected
5.1 Select paragraph  [Text body, German (Germany)]
5.2 Menu Tools > Language > Hyphenation...
5.3 Message "Hyphenation completed"
Pop-up window with dialog 'Hyphenation (German (Germany)) [Kai-sertum] etc.
The hyphenation for German (Germany) could be enabled as follows:
Go to <Program Files>\<LibO_340>\share\extensions\dict-de-DE\...
Replace 'hyph_de_DE.dic' (v2011.05.05) with hyph_de_DE.dic (v2010.12.04)
So it seems to be a bug with the German (de-DE) dictionary
(Not tested: de-AT, de-CH)

Tested with 'nightly' LibO 3.4 v2011-05-23 [on WinXP]
Automatic and manual hyphenation
[German (Austria), German (Germany), German (Switzerland)]
work fine with the modified dictionaries 'hyph_de_AT.dic', 'hyph_de_DE.dic', 'hyph_de_CH.dic'.
