2d array argument to type-parametric function raises ArrayStoreException

[scabug]

The following code:

def transpose[A](arr: Array[Array[A]]) = {
  for (i <- Array.range(0, arr(0).length)) yield
    for (row <- arr) yield row(i)
}

var my_arr = Array(Array(1,2),Array(3,4))

for (i <- Array.range(0, my_arr(0).length)) yield 
  for (row <- my_arr) yield row(i)

transpose(my_arr)

results in
{code}

It looks related to 1192, but that bug is supposed to be fixed in my release (2.6.0-RC2)
