Comment 6 for bug 1303139

Any crasher bug in upstart is a very serious problem which we take seriously. While the issue is resolved for you (since the upgrade is now over), it's important that we find out the cause of the crash on your system, so that it doesn't happen to others.

I understand that you don't have any crash files in /var/crash for this. That's strange, and I'm not sure why that's the case. But there are a few other things we can look at to try to reproduce the problem.

Assuming you were upgrading from 13.10 to 14.04 using update-manager, you should have log files in /var/log/dist-upgrade. Can you please attach the apt.log. apt-term.log, and term.log from this directory?

There have not been other mentions of this bug being seen when upgrading to upstart 1.12, so it is clearly not trivial to reproduce. It may help in reproducing this bug to have a complete copy of your upstart configuration. Can you tar up the contents of your /etc/init directory (tar zcvf ~/upstart-configs.tgz /etc/init) and attach the resulting tarball?
