I think, I've found a 'quick&dirty'-solution:

In the \print_all_bug_page_word.php search for this 2 lines (lines 112/113)

display the available and selected bugs

if ( isset( $t_bug_arr_sort[$j] ) || ( $f_show_flag==0 )) {

and replace it with:

$filtered_bug_id = $t_bug_arr_sort[ ($result[$j]['id']) ];
if ( isset( $filtered_bug_id ) xor ( $f_show_flag==0 ) ) {

In the \print_all_bug_page_excel.php search for this line (164)

if ( isset( $t_bug_arr_sort[$i] ) || ( $f_show_flag==0 ) ) {

and replace it with:

$filtered_bug_id = $t_bug_arr_sort[ ($result[$i]['id']) ];

display the available and selected bugs

if ( isset( $filtered_bug_id ) xor ( $f_show_flag==0 ) ) {

Could someone check this and tell me, if it really works?
-> I would not write this lines, if it would not work for me .-)

Fixed in CVS.

print_all_bug_page_excel.php -> 1.49
print_all_bug_page_word.php -> 1.60
