Backup & Restore giving error ProgrammingError: (1146, "Table 'site1.local.tabSessions' doesn't exist")

I am getting error while restoring backup. Following error is showing up
_mysql_exceptions.ProgrammingError: (1146, “Table ‘site1.local.tabSessions’ doesn’t exist”)

Complete error stack is here erpnext@LifePlus7:~/frappe-bench/sites$ ../env/bin/frappe --backup site1.local - Pastebin.com

Please decompress the sql.gz file first (using gunzip) before passing to --restore.
