    Hi Nickolay,

    I was hoping you could help me with something if you have a moment. I'm trying
    to get jsgf working with OpenEars and I'm getting a crash when I reference a
    .gram file. It's probably something basic. This is a known-working
    implementation of Pocketsphinx when used with a .lm and .dic created with the
    language tool. The hmm is hub4wsj_sc_8k. I've also tried it with no ds,
    kdmaxdepth, maxhmmpf, maxwpf or topn settings to rule out conflicts. Here is
    my log leading up to the crash:

    You didn't specify dictionary file, you still need to do that.

    I also suggest you to try latest pocketsphinx, in this particular situation it
    will give you more precise error description.

    Ha, that certainly was something basic. Thanks Nickolay, all working now.
