Why does suggestd service keep crashing ?

Hi,

After installing El Capitan I get crash reports every 3-15 seconds about the suggestd process dying. I'm not sure what this process

does, but whatever it does, it does it often and apparently not very good. I'm thinking it has to do with predictive search suggestions

in Spotligt, Safari ... etc

Any one else seen issues with this and/or have any suggestions on actions to take (that do not involve a crowbar).

Cheers,

Niklas
