Running bifrost on Ubuntu 14.04 LTS results in segmentation fault

[Julia Kreger]

Encountering a segmentation fault running the test script on 14.04LTS upon the step where shade installation is taking place with a -I parameter on the command forcing re-installation.

19:31 < TheJulia> cinerama: Your on 14.04LTS right?
19:31 < cinerama> TheJulia: yep
19:31 < cinerama> TheJulia: so the thing that breaks it is including "-I"
19:31 < cinerama> TheJulia: if i run it with --no-cache-dir i'm good
19:32 < cinerama> TheJulia: it complains about ownership of ~/.cache/pip/http and exits 139 without that

I've experimented with this a bit trying to drill down to the bug. It appears to be a problem with decoding the json containing the output of the command run, which happens at /opt/stack/ansible/lib/ansible/utils/__init__.py line 547. Unfortunately I was not able to isolate what in particular is going wrong.

Running pip either without the "-I" option or with "--no-cache-dir" seems to resolve the issue. Since supplying "-I" is slowing down our run Julia and I agreed that the best way to get things in order would be to omit it.

In the medium term, I'd like to look at using ansible's pip module rather than using command to run pip.

Also, for the record, pip install -I runs fine by itself - it's just causing ansible-playbook to segfault.
