Length of primetext causes it to fail

[cjsweeney]

Hi,
The model works wonderfully for primetext up to a certain length, after which it produces this error:

lua: bad argument #1 to '?' (empty tensor at /tmp/luarocks_torch-scm-1-oGU5EX/torch7/generic/Tensor.c:911)
stack traceback:
[C]: ?
[C]: ?
./sample.lua:116: in main chunk
[C]: ?
[C]: ?

Is there a way to make any length primetext work for seeding the model?
