Error when enabling faceted_search_views module

I've implemented faceted views on my site and it has done exactly what I wanted it to do!! Love it!

However I experienced a problem when configuring: if I enable faceted_search_views part of the module I get the following error message and my site becomes inaccessible. I had to delete the offending file to get access again.

Parse error: syntax error, unexpected T_OBJECT_OPERATOR, expecting ')' in /home/httpd/vhosts/mysite.co.uk/httpdocs/modules/faceted_search/faceted_search_views.module on line 117
