[Evolution] Calendar stuck in "Searching for existing versions of this appointment"

[Ignacio Mas Ivars <nacho kth se>]

Hi all,
I am having a big in the calendar function that avoids me from adding
new events to my local calendar. Basically, since I upgraded to Evo
2.11.2 with evo-data-server 1.11.2, when I receive a new invitation, the
mail view freezes displaying  "Searching for existing versions of this
appointment", and the four buttons are greyed out, so that I can't do
anything with the invitation.

Past events are still shown properly in the calendar and I am able to
open an already accepted invitation and forward/update it... but no way
to add new ones.

The output in the console is the following when I start evo:

** (evolution:6413): DEBUG: mailto URL command: evolution %s
** (evolution:6413): DEBUG: mailto URL program: evolution
libnm_glib_nm_state_cb: dbus returned an error.

and there it stays. Evo does not freeze and I can still open other mails
without problem...

Any ideas?
Thanks for the help!
