PocketSphinx Segmentation Fault

[Cerin]

The ps_test.py file included in the python-pocketsphinx doesn't work out of the box since it refers to paths ../model/hmm/wsj1, ../test/data/wsj/wlist5o.nvp.lm.DMP, and ../model/lm/cmudict.0.6d, which don't seem to exist anywhere in the other pocketsphinx packages.

The most similar paths I could find, provided by the pocketsphinx-hmm-wsj1 and pocketsphinx-lm-wsj packages, are /usr/share/pocketsphinx/model/hmm/wsj1, /usr/share/pocketsphinx/model/lm/wsj/wlist5o.3e-7.vp.tg.lm.DMP, /usr/share/pocketsphinx/model/lm/wsj/wlist5o.dic.

However, replacing the paths in ps_test.py with those results in the error:
