The "Page Title List" at ./admin/reports/page-title seems to require an immense amount of memory. We're at 450M (ini_set('memory_limit') in settings.php) and get an WSOD when accessing this page. Apache's error log:

…PHP Fatal error:  Allowed memory size of 471859200 bytes exhausted (tried to allocate 71 bytes)…

Maybe there is a way to code this report, whatever it is supposed to show, in a less memory consuming way so that it can be actually used?

Thanks!
