Comment 9 for bug 90258

After some research, I found http://bugzilla.gnome.org/show_bug.cgi?id=268533, it seems a bit similar to this (although it is marked fixed for 1,5 years now).

attaching gdb to the running e-d-s-process, I get the following:

---
(gdb) print e_data_cal_factory_get_n_backends(e_data_cal_factory)
$1 = 0
(gdb) print e_data_book_factory_get_n_backends(e_data_book_factory)
$2 = 3

Note: I have configured 3 Adress-Books on the current account, all seem to be kept open by something even after logout from session.
