rsnapshot LVM backup fails at line 3720

[Jon Stumpf]

This error is received for each LVM listed in the rsnapshot.conf file:
        Use of uninitialized value $linux_lvm_oldpwd in concatenation (.) or string at /usr/bin/rsnapshot line 3720.
        chdir()
        Use of uninitialized value $linux_lvm_oldpwd in chdir at /usr/bin/rsnapshot line 3722.
        Use of chdir('') or chdir(undef) as chdir() is deprecated at /usr/bin/rsnapshot line 3722.

The error actually occurs at the assignment of $linux_lvm_oldpwd on line 3543.
        $linux_lvm_oldpwd = $ENV{PWD};

$ENV{PWD} returns nothing. This was not the case in December and this started failing for me sometime around Jan 10th, 2014. I am not a Perl programmer but the documentation I found states that the proper way to get the current working directory is to call cwd() and NOT use $ENV{PWD}.

I replaced the offending line with the following:
        $linux_lvm_oldpwd = cwd();

I no longer experience the issue.
