High CPU usage
Since the 4.17 series (currently using 4.17.3), I've sometimes noticed large slowdown on my system. Checking System Monitor shows Tumbler sometimes gets stuck using 50-100% of the CPU forever.
Here is a file that it seems to get stuck on, resulting in permanent high CPU usage.
I put this in a folder of its own and browsed it in Thunar, watching Tumbler in gnome-system-monitor. When going to the folder with this file, Tumbler CPU usage jumps to 30%+ (which I think is about 3 or so threads of my CPU at 100%) and stays there. Checking "Open Files" in system monitor shows multiple instances of the file open (and lots of extra "local sockets" if either of those things are relevant).
Let me know if there's anything else I can do to test this or give more info (or if these should be two separate issues). Thanks.
