Running more than one instance of Evince (reprise)

[Federico Fanton <federico panizzolo it>]

Hi all,
coming from this thread:
http://mail.gnome.org/archives/evince-list/2009-April/msg00016.html

I'm launching evince in this way:

dbus-launch --exit-with-session evince path.pdf

I'm having a weird problem though.. When I close evince, ps shows that 
the process is still running.. :/ So if I launch evince repeatedly in 
that way, after a while it refuses to open up altogether.. Too many 
instances maybe. Anyway, is this expected behaviour? Is there a way to 
avoid it?
Many thanks :)
