Ship it!


Code looks fine to me now. I'm to lazy to try and test this right now, so assuming you've tested it and can't see any regressions, this is good to commit.

Please also commit the extra lines to telepathy-testlib's nepomukserverrc as well.

If dependencies are not met t-i-d sometimes crashes (for example if nepomukserver is started after t-i-d) and sometimes hangs (for example if t-i-d is started after nepomukserver but before the services are initialized)

Checking if the service is available should be mandatory for all telepathy-kde apps, because otherwise they might be using outdated data (for example contact list will show for contacts the status they had last time that t-i-d was running)
