Public bug reported:

Currently, the top crasher reported on arm for the phones is in url-
dispatcher:

https://errors.ubuntu.com/problem/e17057d970fd4d64e71eb28c6f18b8a6468df471

This is a recoverable error, reported by url-dispatcher's explicit
"recoverable problem" handling.

The problem is, a large number of these are being reported against
*upstart* as the package.  They're being correctly included in the right
bucket, but since the package is listed as upstart instead of url-
dispatcher, the version information is a bit junk.

url-dispatcher's handler only sometimes calls
/usr/share/apport/recoverable_problem with a pid.  Sometimes it calls it
without one.  In that case, /usr/share/apport/recoverable_problem looks
at the parent pid.  However, if url-dispatcher *exits* before
recoverable_problem processes the request, recoverable_problem will be
reparented to upstart.

There may be an underlying issue causing url-dispatcher to exit
abnormally here, which we are subsequently not capturing.  But I think
url-dispatcher should be unconditionally passing a PID, to avoid this
misbucketing.

The other option would be to spawn recoverable_problem synchronously, to
make sure the parent process doesn't exit before it's had a chance to
look at it.  That obviously has other tradeoffs, though.
