This definitely looks like a bug.
You should report it but in the meantime you can workaround it by omitting the escape character and doing your own escaping. The following example replaces "\:" with $; (char 032) before parsing and then converts it back:
#!/usr/bin/perl -wl
use strict;
use Text::CSV_XS;
my $row = '0005:A:A2:\\\\string 04\\\\';
# Translate escaped : "\:"
$row =~ s/\\:/$;/eg;
my $csv = Text::CSV_XS->new({'quote_char' => '',
'escape_char' => '',
'sep_char' => ':',
'binary' => 1 });
if ($csv->parse($row)) {
my @fields = $csv->fields();
# Replace escaped chars
s/$;/\\:/g for @fields;
print "$fields[3]\n";
}
else {
print "Parse failed ", $csv->error_input();
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
