Arch Linux

I tried to search for "libespeak.so.1:" and also wanted to search in "Comments". So I clicked on the "Advanced" button to the right of the text field "Search this project for". Under miscellaneous, I enabled the checkbox in front of "Search in comments". I then hit "return" when the cursor was in the text box. This brought me to this URL:

http://bugs.archlinux.org/index.php?string=libespeak.so.1%3A&project=1&search_name=&search_in_comments=1&type[]=&sev[]=&pri[]=&due[]=&reported[]=&cat[]=&status[]=open&percent[]=&opened=&dev=&closed=&duedatefrom=&duedateto=&changedfrom=&changedto=&openedfrom=&openedto=&closedfrom=&closedto=&do=index

But instead of a result, an error message was shown:
