Bug 1324209

Description of problem:
Every time I start the storaged service with systemd, it segfaults. I also can reproduce the error by simply running /usr/libexec/storaged/storaged in a root terminal.

I can reproduce this issue at will if you need further debugging.

This particular instance, I passed the --disable-modules flag, but it happens with or without that flag in place.

storaged-2.2.0-3.el7
