It seems that cancelling a user causes a warning in page_title module (install with all features enabled)
Location: .../en/user/5/cancel
Referrer: .../en/user/5/cancel
Warning: Parameter 1 to page_title_user_cancel() expected to be a reference, value given in module_invoke_all() (line 857 of .../includes/module.inc).

Echofive commentedI confirm than the error occurs when a user is deleted.
The function page_title_user_cancel() invoke the hook_user_cancel().
The parameters used with this function are not correctly implemented.
This post explain the problem and provides a patch.
