Column count of 0 messes up gallery listing on some themes

While using Fotorama, I’ve noticed that hard-setting the columns to “0” (And it seems like the “columns=’1′ ” parameter in the shortcode is ignored) breaks gallery display in certain themes.

iThemes builder themes uses the column count to determine whether they’re at the end of a line, and insert a
. This is done by if ( is_numeric( $columns ) && ( 0 != ( $count % $columns ) ) ), which is running the mod command on 0, which always throws a php error.

Could the columns variable be set to “1” by default without there causing problems?
