Comment 123 for bug 1512120

You are not the only one.
I use 15.10, but 16.04 is obviously also effected.
If you have the 64 bit version, you could try my binary. It also works on 16.04.
Have a look here: https://forum.ubuntuusers.de/post/8172653/
You need to rename the attachment, make it executable, change the owner to root and replace /usr/bin/thunar. A reboot is recommended.

While some users are regularly effected, others seem to have no problems. I read anywhere that it may depend on your view settings (detailed list view with showing of the file date?)
