Interesting.

For others (who don't want to read through 37 comments which demonstrate Lucas 
Maneos' awesomeness in both perseverance and debugging skills!), this boiled 
down to Faheem's app using run-standalone.sh in an upstart script and needing 
to add:

pre-start script
        /usr/sbin/waitdbus system
end script

Faheem, what were you using as the start condition for your upstart script?  I 
would have assumed that if it were anything after "start on started dbus" 
then the waitdbus would be unnecessary.  In particular, I normally use

start on XSESSIONS_STARTING

for user applications, which is long after dbus.

However, adding the pre-start script if you plan to use run-standalone.sh in 
an upstart script seems like a good rule for safety.

P.S. This probably explains a problem I have with taking backups on my test 
N900, which I couldn't understand despite poring over strace output for 
hours!
