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. -- e-d-s does not exit with gnome-session https://launchpad.net/bugs/90258 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
