Version:            (using KDE 4.1.3)
Compiler:          gcc (GCC) 4.1.2 
OS:                Linux
Installed from:    Gentoo Packages

I'm using one Imap account to store my PIM data with two different PCs:
- Gentoo with KDE 4.1.3
- SuSE 11 with KDE 4.1.3

If I add a ToDo on one machine with end date, the ToDo appears on the other machine with distorted end date (the ToDo application isn't able to parse the date) and I have to select an new date. I have this problem in both directions.

I thought this might happen because of different language settings (which would be a Bug, too, since only the GUI should depend on language and not the storage).
However I have the same locale on both maschines:
LANG=en_GB.utf8
LC_CTYPE=de_DE.utf8
LC_NUMERIC=de_DE.utf8
LC_TIME=de_DE.utf8
LC_COLLATE=de_DE.utf8
LC_MONETARY=de_DE.utf8
LC_MESSAGES=en_GB.utf8
LC_PAPER=de_DE.utf8
LC_NAME="en_GB.utf8"
LC_ADDRESS="en_GB.utf8"
LC_TELEPHONE="en_GB.utf8"
LC_MEASUREMENT="en_GB.utf8"
LC_IDENTIFICATION="en_GB.utf8"

I don't have any problems with events, tasks or address book entries.
