Comment 28 for bug 356152

Running that perl script showed that update notifier is
probably getting confused by log rotation!
It's telling me that it won't run update manager
because /var/log/dpkg.log is too new... even when
the darn file is only new because the log was rotated and is zero size.
I'm attaching a (bad) patch showing how this might be worked around.

I think this is an old bug, only exposed in Jaunty because of the change to not showing nonsecurity updates for a week.

Don't know how much of the problem this explains, but it does seem to explain the behavior of two systems I have access to, at least today.
