| Subject: | get_envelope() fails when subject line ends with backslash |
Using Mail::IMAPClient, If the last character of a message's subject
line is a backslash, calling get_envelope() fails.
This is 64-bit perl 5.10.1 on CentOS 6.3. Confirmed the problem happens
with multiple IMAP servers, including Microsoft Exchange 2010.
When the problem occurs, a separate bug is causing this warning:
Use of uninitialized value $bs in concatenation (.) or string at
/usr/local/share/perl5/Mail/IMAPClient.pm line 2032.
That line is:
$self->_debug( "get_envelope: msg $msg returns ref: " . $bs || "UNDEF" );
Since . is higher on the order of operations than || this needs
parentheses around the ($bs || "UNDEF").
With debugging turned on, the relevant bit looks something like this:
