./install.sh: line 350: [: too many arguments

When I install virtualmin pro 50 at the very end of th einstallation in the shell I get the following:

Installing dependencies using command: /sbin/yast -i webmin usermin postfix bind perl-spamassassin spamassassin procmail perl-DBI perl-DBD-Pg perl-DBD-mysql quota openssl mailman subversion ruby mysql mysql-Max mysql-administrator mysql-client mysql-shared postgresql postgresql-pl postgresql-libs postgresql-server webalizer apache2 apache2-mod_fastcgi apache2-mod_perl apache2-mod_python apache2-mod_php4 apache2-mod_ruby apache2-worker apache2-prefork clamav awstats dovecot cyrus-sasl proftpd

Installing Virtualmin and all related packages now using the command:
/sbin/yast -i virtualmin-base
./install.sh: line 350: [: too many arguments
Installation completed.
