You can turn on LWP debugging:
require LWP::Debug; LWP::Debug::level('+');
if you haven't already.
Update: Forgot the require LWP::Debug the first time

    I hadn't thought to set LWP::Debug (and did you know that Perl and LWP doesn't deal with LWP::Debug at all?), but now I have, and am getting much the same result when the proxy statement is removed. Without proxy, the output from LWP::Debug is:
    LWP::UserAgent::request: () LWP::UserAgent::send_request: GET ftp://user:password@ +oing/ LWP::UserAgent::_need_proxy: Not proxied LWP::UserAgent::send_request: ftp URLs are among LWP::UserAgent=HASH(0 +x83ae480)'s allowed protocols (ftp http) LWP::MediaTypes::read_media_types: Reading media types from /my/lib/pe +rl5/site_perl/5.6.1/LWP/media.types LWP::Protocol::ftp::request: () LWP::Protocol::MyFTP::new: ()
    and here the debugger dies, along with the script.

    With the proxy statement left in, I get:

    LWP::UserAgent::request: () LWP::UserAgent::send_request: GET ftp://user:password@ +oing/ LWP::UserAgent::_need_proxy: Proxied to LWP::UserAgent::send_request: http URLs are among LWP::UserAgent=HASH( +0x83d28b0)'s allowed protocols (ftp http) LWP::Protocol::http::request: () LWP::Protocol::collect: read 315 bytes LWP::Protocol::collect: read 4096 bytes LWP::Protocol::collect: read 4096 bytes LWP::Protocol::collect: read 2954 bytes LWP::Protocol::collect: read 1460 bytes LWP::Protocol::collect: read 660 bytes LWP::Protocol::collect: read 32 bytes LWP::UserAgent::request: Simple response: OK
    and the debugger stays alive and ready to proceed.

    On the off-chance this was an artifact of the debugger, I ran without the -d flag and sprinkled in some print statements. This didn't produce any change--LWP::Debug gave the same output and I died in the same place.

    So at this point, I'm slightly stumped. I suppose my next move is either to give up and say "What the heck do I care? It works, doesn't it?" or step laboriously through the LWP code itself to see where it dies.

    I'm certainly open to a better idea than either of those two.

    Afterthought: I'm running 5.6.1. LWP is version 5.63.
