Comment 37 for bug 275432

There are various situations where polkit_context_init() fails:

 - PolicyKit daemon is not installed. This happens e. g. in a Debian or Ubuntu server installation (we split off the library to minimize dependencies)
 - PolicyKit.conf does not exist or is invalid

Right now, CK aborts with

However, I think that's too strong. Even without PK, CK is still useful for session tracking. If this happens, CK should behave as if it was compiled without PK support, not abort completely.
