It would seem that this bug is related to tracker and that it has happened before (see archlinux forum post: https://bbs.archlinux.org/viewtopic.php?pid=937784).
I can confirm this by running `sudo mv /usr/lib/nautilus/extensions-3.0 /libnautilus-tracker-tags.so /usr/lib/nautilus/extensions-3.0 /libnautilus-tracker-tags.so.bak` I used to have problems when opening the properties dialog on large tif files, but after removing the nautilus tracker library, all seems well. This points to a problem in tracker, I would think. Unfortunately, I don't know much about how it works. I can just offer the workaround for now. josh@josh-ThinkPad:~/.local/share/applications$ tracker-info -V Tracker 0.14.1 This program is free software and comes without any warranty.
