Comment 2 for bug 1580673

Mh I think the issue is upstart and dbus-session related more than an unity issue.

In fact:
 $ ls /proc/$(pgrep -u $USER dbus-daemon | head -n1)/cwd -l
 lrwxrwxrwx 1 marco marco 0 mag 31 15:58 /proc/940/cwd -> /

Thus the process that has the role of launching these kind of apps, and it's the one responsible for setting the proper CWD.

Unfortunately, it seems that just calling chdir in /usr/share/upstart/sessions/dbus.conf is not enough.
