Accepting calendar invitations fails with "Unable to send item to calendar '<calendar-name>'. No such interface `org.gnome.evolution.dataserver.Calendar' on object at path /org/gnome/evolution/dataserver/Calendar/12376/19"

Status changed to 'Confirmed' because the bug affects multiple users.

I've found the same error and behavior on oneric 3.0.0-12-generic-pae i386. If I can provide any information that might be helpful please let me know.

Even if I try to add the event to my personal, and off-line calendar, I get the same error. Is not only a problem with Google Calendar.

As a temporary solution, killing the e-calendar-factory process and restarting Evolution makes possible to a accept invitations again.

same problem here .. it seems that e-calendar-factory crashes with SIGSEGV here is the stack trace

Any progress on solving the bug? Did anyone find a workaround?

Workaround : create new calendar and use it

The workaround is working though it means I cannot use all dates in the old calendars and for some reason copy does not work for my appointments.
Evolution 3.2.2

I upgraded to 11.11 several weeks ago, and everything has been working fine. My calendar is just a default calendar on this computer (that is, not a google calendar as in the original report). Just yesterday it started happening, and now I cannot add any calendar events, which is going to be quite a problem. Creating a new calendar is not really a viable workaround.

As was mentioned, after the first (do-nothing) click on accept, the factory process is still running. After the error, that process is gone and a new one has been created.

Is there anything we can do to help troubleshoot this issue? It makes Evolution more or less unusable for me.

Same problem here on Ubuntu 11.10 32 Bit using Evolution 3.2.2, what information can I contribute to help solve the issue?

Same issue here, using Evolution on Oneiric against Radicale (a simple CalDAV server).

This makes Evolution completely unusable for scheduling meetings. What can be done?

I have the same problem. Please fix!

Seems I found a workaround. When starting Evolution from console I saw an error message saying that ~/.evolution/tasks could not be deleted. That dir was empty. I deleted it, shutdown Evolution (some process hung after rmdir ~/.evolution/tasks, killed them), started Evolution, it then said "Migrating cached data, Migrating config data, Migrating local user data". I could then accept an invitation and save it to my personal calender where it now appears in. I don't know whether this solved the issue permanently or if it will recur.

@morgenbart: I don't even have that directory, and if I remember correctly I have already tried deleting all directories related to evolution.

Happens to me as well: Linux Mint 12, Cinnamon desktop, Evolution 3.2.2 on 64-bit 3.0.0-12-generic.

same problem on ubuntu 11.10 with a google calendar

same problem on mint lisa and this bug is almost one year old, any chance to have a fix?

Also has the problem on ubuntu 11.0 , when someone use outlook send me the calendar. It will says something like that.
