Hi Bastien,
by default the fprintd installs the pam_fprintd into the /usr/lib64/security, whil egentoo searches them in /lib/security.
So I simply simlinked it to the correct location /usr/lib64/security/pam_fprintd.so to /lib/security/pam_fprintd.so
I've removed the symlink, and copied the file, but it does not change anything, the same error appears.
As you asked, recompiled some of the packages with "-O1 -gddb" and "nostrip" options.
So here is the bt full output of the gdb

** Message: debug on
process 22019: The last reference on a connection was dropped without closing the connection. This is a bug in an application. See dbus_connection_unref() documentation for details.
Most likely, the application was supposed to call dbus_connection_close(), since this is a private connection.
