Tracker error slows down system and breaks suspend to RAM

[Wolf Rogner]

By default Budgie installs tracker.

$ tracker status

This slows down the system tremendously. As a side effect, the system can't go into suspend to RAM mode (wakes up every second)

Is it always that same file that causes it?

if so run the following on your problematic file and file an upstream bug at bugs.gnome.org with the output. If you do so please provide a link to the upstream bug, so we can add it onto this bug report.
tracker extract -v debug <FILE>
