[Debconf-devel] Bug#480533: Bug#480533: "uninitialized value" warnings from Perl during install

[Joey Hess]

I don't see any protocol problems in the log.

        debug developer => "<---- $reply";
        my ($tag, $val) = split(' ', $reply, 2);

The first line of code succeeded and printed $reply, which was the "0 OK".
In the second line of code, $reply has somehow become undef.
I don't understand how that could happen! 

Apparently, perl's utf-8 output layer is coming into the picture -- that's
where the utf8_heavy comes into play. Perhaps it is somehow unsetting $reply.
