Please describe the problem:
Running tracker-properties fails to load the tracker properties from the config file because the GKeyFile configuration variable is not initialized.

Steps to reproduce:
1. Create new configuration by running trackerd
2. Run tracker-properties
3. Many glib assertion errors about g_key_file* functions


Actual results:
The preference window only shows the default configuration.  Any changes to the config file are not loaded.

Expected results:
The preference window only shows the default configuration.  Any changes to the config file are not loaded.

Does this happen every time?
Yes
