[Evolution] Deleting multiple (real many) same calendar entries

[Stephan Skrodzki <skrodzki_list stevekist de>]

Hi there,

after trying to sync an overnight flight entry  between Evo and my palm,
it ended up in having this entry now in every day of my calendar as a
_single_ entry (not as a reoccurring one!). 

Is there a way to delete such an entry automatically?

I guess I will move soon to a local funambol instance for syncing
between Palm and Evo. The palm syncing right now works really to bad:
adresses which I change in Evo are not updated, Calendar produces
fancies like above, Notes from Evo are not synced to palm... 

Anybody made better experiences with funambol for this?

Regards
 Stephan
