ShowcaseView - width and height must be> 0

Research has proven fruitless as all other references to this error seem to be reliably repeatable; I cannot consistently repeat this error:

As I said above, this error does not occur all the time. It seems to happen (but not quite) 2-3 times, then 2-3 runs pass without problems.

Here is my resource file:

And here is my java. Note that I even tried to hardcode the width and height for my ViewTarget, but I still get conflicting errors. I also tried to create placeholder TextViews in my resource file but still don't go.

        PersonListFragment fragment = new PersonListFragment();
        Bundle args = new Bundle();
        args.putString(TAG, tag);
        args.putLong(INDEX, index);
        fragment.setArguments(args);
        return fragment;
    }

I'm sure this is a definite problem with how android pulls objects, but I have no knowledge to know why they are drawn correctly on some runs but not others.

Please do not ask this question unless you are sure if asked elsewhere regarding an intermittent problem :-)

Any help is appreciated.
