[Tracker] Tracker error unkown tokenizer

[Rick van der Zwet <info rickvanderzwet nl>]

Hi Folks,

$ tracker search foo
Could not get search results, unknown tokenizer: TrackerTokenizer

$ tracker --version
Tracker 1.7.3

I also tried to reset:
    $ tracker reset -r

Yet the same result applies. Any hints on what I might be doing wrong?

Best regards,
/Rick
