evolution, Objekt ungültig

[arton]

Hi,

I'm using evolution and suddenly I can't insert new dates.

The Error is

Der Kalender »Kontakte : Geburts- & Jahrestage« konnte nicht geöffnet werden
Objekt ungültig

What's the problem?

Please launch evolution from a terminal and try to insert a new event. Do you get an error message in your terminal?
You should also consider to visit www.debianforum.de as most of the users here aren't able to read German error messages

It is not very difficult to use copy paste, and translate the error message, but it is something the OP should do, and could do , I did it this time for them :

From:Der Kalender »Kontakte : Geburts- & Jahrestage« konnte nicht geöffnet werden
Objekt ungültig
===========================
The calendar »Contacts: Birthdays & Anniversaries« could not be opened
Object invalid

Since the OP could not even use google translate, it makes me wonder if they even tried to do any searches:
On Debian, using evolution and suddenly I can't insert new dates
There seem to be a lot of results, I don't have time to go through them all looking for something that may be similar or the same as the problem the OP has, I did notice a "bug" list, and there seem to be a lot of them. I don't use this kind of software my self, so don't really know. maybe someone else will.
