Tvheadend

I have just upgraded my stable release to the daily build, then removed the .hts folder, reconfigured dpkg and started redoing the configuration.
I added the 4 standard ziggo muxes and let tvh scan to detect other muxes referenced in the existing muxes, after a while I went to check if it was done and noticed that it keeps adding the same mux over and over again.
When I stopped the scan it had added the same few muxes at least ten times and I had duplicates of the same channels on all of them.
Looks like tvh doesn't realise it already has the discovered mux and just adds it each time.
