23001	invoking post_gallery filter causes segfault	gcrumb		"Attempting to change some default values in the gallery_shortcode function. I copied and pasted it into functions.php, changed the values of the 'columns' and 'size' attributes, and then added the filter hook:

add_filter('post_gallery', 'pipp_gallery_shortcode', 10,1 );

Reloading a post with a gallery included causes a segmentation fault:
user@host:/srv/www-apps/folder/wp-content/themes/pipp$ sudo tail /var/log/apache2/error.log
[Wed Dec 19 16:40:06 2012] [notice] child pid 25830 exit signal Segmentation fault (11)

Commenting the add_filter line causes the post to display properly.
