I cloned and installed the the development version and it doesn't seem to have this problem. Installing with pip does not work as it is an older version. @drj11 - can you update the package on PyPI? Not only is it a problem for using pdftables on its own, the messytables package also depends on it.

The development version doesn't have the problem because it's using poppler as the default backend. I'll send pull request that fixes the pdfminer api change in case anyone wants to use that as the backend.
