      Checking some, the reason is pretty obvious:

      This player just learned summoning, thus his skill is 1.

      The player worships Mostrai, so summoning repelled.

      So player lever becomes (see spell_util.c:caster_level) 1 - 2 (repelled)

      Min level to cast (min_casting_level) is 1 - 2 -> -1 checked against <1

      So he simply can't cast the spell, and can't level up alone, need to party.

      I think the best way to fix is to check caster_level and return at least 1.
     
     
  Just for the record, that is now done.

  This is done to fixes some other bugs, most notably some divide by zero bugs 
for functions that just divide by caster_level()
