Situation is a bit unclear for me, do you mean that when you start your
application without X, you get an error, or that if one user is running applications, second can't start it?

Please also note that plain X session doesn't start b-a-s, it it done by gnome
seesion. Is there difference of startup of application from plain X session and
from gnome session?

I think you'd want to pass argc argv to bonobo_init. Also there is no
need to chech for bonobo_is_initialized.

if you've already done bonobo initialization there is no need to initialize
bonobo_activation. Please try to make your code more simple. Look at test-speech, there is only one call to bonobo_init. But you need to 
make a call of bonobo_activate, I think. I don't know why it's missing
in test-speech, but it should present, probably, it's a bug. Take a look at bonobo sources in samples/echo, where small example of bonobo usage is located.

Looks like you are doing something wrong. Try more closely follow the examples, I think everything should work.
