#7 Unhandled error on trying to list local queue

Transcript follows:

[qmhandle-1.2.0]# ./qmHandle -L

readline() on closed filehandle MSG at ./qmHandle line
233, <MSG> line 6 (#1)
(W closed) The filehandle you're reading from got
itself closed sometime
before now. Check your logic flow.

Use of uninitialized value in substr at ./qmHandle line
234, <MSG> line 6 (#2)
(W uninitialized) An undefined value was used as if
it were already
defined. It was interpreted as a "" or a 0, but
maybe it was a mistake.
To suppress this warning assign a defined value to
your variables.

To help you figure out what was undefined, perl
tells you what operation
you used the undefined value in. Note, however,
that perl optimizes your
program and the operation displayed in the warning
may not necessarily
appear literally in your program. For example,
"that $foo" is
usually optimized into "that " . $foo, and the
warning will refer to
the concatenation (.) operator, even though there
is no . in your
program.
