Because print_r is a direct output function. You'd need some sort of buffering scheme to grab its output in chunks and assign it to a variable or put it in the database or whatever, once per usage.

Try calling "drupal_set_message(print_r(debug_backtrace(), TRUE))" from inside the drupal_set_title() function at "includes/path.inc, line 206".
Thanks for your patience, but I had no luck with this either.
function drupal_get_title() { $title = drupal_set_title(); drupal_set_message(print_r(debug_backtrace(), TRUE))
// during a bootstrap, menu.inc is not included and thus we cannot provide a title if (!isset($title) && function_exists('menu_get_active_title')) { $title = check_plain(menu_get_active_title()); }
return $title; }
and
function drupal_get_title() { $title = drupal_set_title();
// during a bootstrap, menu.inc is not included and thus we cannot provide a title if (!isset($title) && function_exists('menu_get_active_title')) { $title = check_plain(menu_get_active_title()); } drupal_set_message(print_r(debug_backtrace(), TRUE)) return $title; }
result in:

respctively
Parse error: syntax error, unexpected T_RETURN in /var/www/drupal/includes/path.inc on line 239
(is this even "inside the function"?)
function drupal_set_title($title = NULL) { drupal_set_message(print_r(debug_backtrace(), TRUE)) static $stored_title;
results in

function drupal_get_title() { $title = drupal_set_title(drupal_set_message(print_r(debug_backtrace(), TRUE)));
// during a bootstrap, menu.inc is not included and thus we cannot provide a title if (!isset($title) && function_exists('menu_get_active_title')) { $title = check_plain(menu_get_active_title()); }
results in lots of debug output all over the first page I', loading, and then in

Sorry, this is too much guesswork as I don't understand enough about PHP syntax.
E.g. "inside the function" drupal_set_title(check_plain($gallery->name)); probably means somewhere inside the first (), or second (), either before, or after "check_plain", or either before, or after "$gallery->name".
