Thanks for accepting these little patches.

The attached patch changes the window title a little more to display the
program name instead of the full path to the executable.

/usr/bin/firefox (sandbox_web_t)
/usr/bin/evince '/tmp/foobar.pdf' (sandbox_x_t)

after applying the patch titles look like the following:
firefox (sandbox_web_t)
evince (sandbox_x_t)

I played a bit with 'xprop'. I was able to modify the title from outside
the sandbox but not from within. I think it is not possible to change it
from within the sandbox because the title is a property from the main X
(running at :0 ).

kind regards,
