Bug#909362: nautilus: Takes very long time to start and stop when tracker crashes

[Simon John]

I get the same problem in Sid, starting from the terminal gives some 
more info:

Deleting  ~/.cache/tracker/ does seem to fix it.

# systemctl --user status tracker-store
Failed to connect to bus: No such file or directory

Nautilus 3.30 seems very buggy overall - often crashing when opening a 
new tab or window.
