Vocabulary broken

[Benjamin Mesing]

Hello, 

my vocabulary seems somewhat strange. I've tried to purge and reinstall
debtags with no change. The file contains entries of the form:

        Facet: data-exchange
        
        Tag: data-exchange::ata-exchange
        Description: Data Exchange
        Implies: foreignos
        
        
        Facet: foreignos
        
        Tag: foreignos::oreignos
        Description: Foreign OS and Hardware
        
        
        Facet: net
        
        Tag: net::et
        Description: IP Networking
        Implies: netcomm
        
        Facet: netcomm
        
        Tag: netcomm::etcomm
        Description: Network and Communication
        
Obviously there are no packages having those tags. 
The bad vocabulary is annoying when using packagesearch, since the
facets (foreignos, netcomm,...) are displayed in the facet list.
Debtags-edit does also display those facets/tags.

It would be great if this could be fixed before etch.

Regards Ben
