[Bug 933692] [NEW] dbind: Call to "GrabFocus" returned signature b; expected u

[Nagappan Alagappan]

Public bug reported:

Steps to reproduce:

Install latest LDTP
Enable accessibility
Logout once and login back, if just enabling accessibility, else ignore this step
export LDTP_DEBUG=2 in one gnome-terminal (Ubuntu 12.04)
ldtp

In second terminal

python
>>> from ldtp import *
>>> launchapp('gedit')
>>> click('*-gedit', 'btnOpen')

In first terminal, you will notice the following stack trace:

dbind-WARNING **: dbind: Call to "GrabFocus" returned signature b; expected u

Note: This worked on Ubuntu 11.04, but on that we can run the test with
at-spi1. This has to be fixed, else this will block automated testing in
Ubuntu 12.04

I had discussion with upstream authore Mike Gorse, he suggested that the
latest at-spi2 has the fix for this.
