[php-maint] Bug#770179: sessionclean: sed: invalid option -- 'z'

[Thibaut VARENE]

Package: php5
Version: 5.4.35-0+deb7u1
Severity: normal

unattended-upgrades upgraded php5 on my machine last night, and since then I
receive the following email every 30 minutes:

Cron <root@>   [ -x /usr/lib/php5/maxlifetime ] && [ -x /usr/lib/php5/sessionclean ] && [ -d /var/lib/php5 ] && /usr/lib/php5/sessionclean /var/lib/php5 $(/usr/lib/php5/maxlifetime)

sed: invalid option -- 'z'
Usage: sed [OPTION]... {script-only-if-no-other-script} [input-file]...

 -n, --quiet, --silent
                suppress automatic printing of pattern space
 -e script, --expression=script
                add the script to the commands to be executed
 -f script-file, --file=script-file
                add the contents of script-file to the commands to be executed
 --follow-symlinks
                follow symlinks when processing in place
 -i[SUFFIX], --in-place[=SUFFIX]
                edit files in place (makes backup if extension supplied)
 -l N, --line-length=N
                specify the desired line-wrap length for the `l' command
 --posix
                disable all GNU extensions.
 -r, --regexp-extended
                use extended regular expressions in the script.
 -s, --separate
                consider files as separate rather than as a single continuous
                long stream.
 -u, --unbuffered
                load minimal amounts of data from the input files and flush
                the output buffers more often
     --help     display this help and exit
     --version  output version information and exit

If no -e, --expression, -f, or --file option is given, then the first
non-option argument is taken as the sed script to interpret.  All
remaining arguments are names of input files; if no input files are
specified, then the standard input is read.
