Re: [g-a-devel] Unknown CORBA exception?

["Quiring, Sam" <Sam Quiring windriver com>]

Will, Nagappan,

 

This is to confirm what Nagappan said - I installed Accerciser onto my Ubuntu system.  The 9th application shows up as <dead>.  It is the 9th application that is causing at-spi to display a message to stderr in my code.  Code and output shown below.

Hi Will,

This happens in most of the Ubuntu / RHEL systems, 
some of the application is listed as <dead> in accerciser. In Python, we 
don't notice them, as we can handle this in try / except block, but in C, we 
have this limitation :)

Thanks
Nagappan

Hi Sam:

I wonder if the application is misbehaving.  Try looking at the desktop
via accerciser and see what it shows.  In addition, in your code, try
printing the accessible name of each object as you get it.  It might
provide some insight into which application might be the source of the
problem.
