Comment 1 nicholas 2016-02-23 14:47:24 UTC

I believe the problem is fixed. I suspect the use of 'chrome>tools>add to desktop' was the root cause (it created a file with a very garbled name)

The fix was to simply flush the baloo database:
[completely remove the bad file first]
balooctl status (check baloo responds, reboot if not)
balooctl disable
balooctl enable
balooctl status (to check it is indeed rebuilding)
