ldaphelp.css brakes functionality of dblog

Hi,

I've just noticed a line in the ldaphelp.css file brakes the functionality of dblog entry. You are not able to filter on "type" in the dblog screen, because the following CSS entry is hiding it (display: none):

form#dblog-filter-form div#edit-type-wrapper,
table#admin-dblog th img
{ display: none;}

Please don't use such a generic CSS entry as this brakes the functionality of a core module
