Problems migrating RT#70211 - empty subject and some comment bodies

[timbunce]

I'm trying a dry-run on the devel-nytprof queue. It looks like it's working well (thanks!) but I did encounter a case it has problems with: RT#70211

Use of uninitialized value $subject in numeric le (<=) at /Users/timbo/repos/zzz-rt-to-github/rt-to-github.pl line 142.

    I can reproduce in perl 5.14 but not 5.16 (or 5.17) so I'm inclined to consider it a perl bug.
    I'll dig a little deeper anyway to try to identify the cause and see if a workaround is possible.

An empty subject and some empty comment bodies.
