 I had a copy-paste error go a little bit more wrong than I'd have
 expected. This query reproduces the problem (this will segfault your
 server!):

 {{{
 select
   st_mapalgebra(
     c.rast,
     '8BUI',
     '[rast2.val] + 1'
   ) as rast
 from st_addband(st_makeemptyraster(100, 100, 0.0, 0.0, 1.0), 1, '8BUI') as
 c (rast);
 }}}
