Code review comment for lp:~meese/pantheon-photos/fix-vala26

"set_default_icon_list ((owned) pixbuf_list);" should be
"set_default_icon_list (pixbuf_list.copy ());"

Explicitly use "public" for the struct-fields instead of just dropping the "private".

*No* need to touch "private const int NO_SCALE = 0;"
