FTR this was fixed upstream by bumping the default name recursion level
from 30 to 50:

Bug description:
In Ubuntu 17.04 there seems to be a problem with "file":
$ file test.jpg
test.jpg: ERROR: JPEG image data, JFIF standard 1.01, resolution (DPI), density 240x240, segment length 16, Exif Standard: [TIFF image data, big-endian, direntries=8, description=Picture saved with settings embedded., orientation=upper-left, xresolution=148, yresolution=156, resolutionunit=2, software=Adobe Photoshop Lightroom 6.1.1 (Windows), datetime=2017:08:17 11:16:47] name use count (30) exceeded
This problem was reported in Fedora a couple of years ago:
https://bugzilla.redhat.com/show_bug.cgi?id=1201630
I found out about the problem when the Astrometry program suddenly
stopped working on jpegs that it was previously able to process. I
cannot say how "file" is supposed to normally output the data. I only
found out about this when the program suddenly broke without any
obvious reason after the upgrade from Ubuntu 16.04 to 17.04. Since
there is another case reported for Fedora I tend to believe that the
problem is indeed caused by "file".
The required data:
$ lsb_release -rd
