creates empty dir after upgrading

[Clark]

After upgrading to innobackupex 2.3.2 an empty directory is created in the same directory where the script is executed

When running the syntax from the command line as root no directory is created, but when running the command from php-cli as root a new empty directory is created each time the script is running

Empty dir:
/var/www/2015-11-21_02-58-58

Version:
innobackupex -v
innobackupex version 2.3.2 Linux (x86_64) (revision id: 306a2e0)

Command line as root:
innobackupex --defaults-file=/var/ini/mysql/my.cnf --user=root --password=xxx --databases="db1 db2 mysql" --stream=tar ./ 2> /var/www/bak/db/innobackupex.log | gzip -c -1 > /var/www/bak/db/2015-11-27-1244_mysql.tar.gz

From php-cli as root:
exec('innobackupex --defaults-file=/var/ini/mysql/my.cnf --user=root --password=xxx --databases="db1 db2 mysql" --stream=tar ./ 2> /var/www/bak/db/innobackupex.log | gzip -c -1 > /var/www/bak/db/2015-11-27-1244_mysql.tar.gz');

I just found out that when running the syntax from the command line the empty dir is created in the home dir..

So no matter if you run the command from php or the command line the directory is always created

Can you provide output of /var/www/bak/db/innobackupex.log and contents of /var/ini/mysql/my.cnf

innobackupex creates empty directory when --stream specified. --stream should imply --no-timestamp.
