These errors indicate a mismatch between your at-spi and the GNOME 2
libraries.

I have seen this happen if I accidentally re-compiled with my
environment set wrong, or if not all of the libraries on my system were
in sync with each other.

I would recommend checking your environment, doing a make clean,
autogen.sh, make install, and trying again.

If that does not solve your problem then you may need a new set of GNOME
2 libraries.

Best regards,

Bill
