Hi, I'm experiencing what is probably the same or a similar problem. I'm getting similar entries in the log, and when I run /usr/lib/at-spi2-core/at-spi-bus-launcher from the terminal it immediately dumps core. I'm attaching a stack trace. It looks like the offending line is the one added by the register-client-early patch. Regards, Matijs
