G'day Neil,

"... does not look like what I expect."

You haven't stated what your expectations are. In the remainder of my post, references to your expectations are just guesses. If they're good guesses, all's well; if not, post your expectations.

In the code

warn "Got bug title [$e->title]"
[download]

you're expecting the return value of $e->title to be interpolated into the string. It doesn't work like that. Here's a quick and dirty example:

$ perl -Mstrict -wE 'my $e = bless {} => "XXX"; say "[$e->title]"'
[XXX=HASH(0x7fc0c9805480)->title]

One way to get what you want is to wrap $e->title in @{[...]}:

$ perl -Mstrict -wE 'my $e = bless {} => "XXX"; say "[@{[$e->title]}]"
+'
Can't locate object method "title" via package "XXX" at -e line 1.

Now an attempt is made to call the object's method. Using this syntax in your warn code may provide a little more insight into what's happening:

warn "Got bug title [@{[$e->title]}]"
[download]

However, it appears to me that the most urgent thing you need to deal with is:
