Cannot load valid object form HDF5
I have a rather weird error. I am essentially running the following code:

``` python
data = pd.read_hdf(filename.h5, pathstring)
```

I have also tried it in two steps

``` python
store  = pd.HDFStore(filename.h5)
data = store.get(pathstring)
```

The problem is that when I am running the code on console/ipython it seems to work fine. but when I run it in a flask app feeding the string query parameters it breaks and raises KeyError saying the object doesn't exist. The path looks fine in HDFView as well.

I am using Continuum's Anaconda python distribution. All relevant packages (pandas, numpy, pytables) are up to date. I am on python 2.7.6 on OS X 10.9 x64
