Hi,

>From those logs, seems that the connection with X dies for some reasons.
Because at-spi is responsible with this, it is an at-spi bug. The patch
I sent to you (the one for gnopernicus) prevents gnopernicus to do
something. It only shows some information for every event.

Bill, what do you think about this bug? In the attachment are 2 files:
  1. patch- a patch for gnopernicus to display information for every
event received by gnopernicus. After displaying, the callback return
(the original gnopernicus code is not executed).
  2. gnopernicus.log - the output with this patch.

Daniel, thanks for your help.

Remus
