dt.rbind() when Frames have arr32() columns?

[lmullany]

I have these two frames:

k1=dt.Frame(id=[1],val=[["a","b"]])
k2=dt.Frame(id=[1],val=[["c","d"]])

I cannot row bind them together.

dt.rbind([k1,k2])

----> 1 dt.rbind([k1,k2])

NotImplementedError: Cannot materialize column of type arr32(str32)

Is there anyway around this?

The array type is under development, so some features may still be missing. Unfortunately, one of them is rbind.
