Bug#563670: jhead: Illegal subdirectory link in Exif header
Singer Michael
Version: 1:2.88-2
Severity: normal
Hi,
When viewing the EXIF data of a photograph is the following error. What does this error message?
How can I avoid this error? Is this a bug or a defective EXIF header?
Regards
Michael Singer

Yes, it looks like a defective EXIF header. Or a bug in jhead :-)
Please attach the BILD1623.JPG file (or another file with the same
problem) so I can reproduce the problem and send it to the upstream
author.
Bye

It looks like the EXIF data is corruped/bogus.
Using another EXIF parser (exifprobe) I have a error reported:

I do plan to close this bug. Maybe you should report the bug to Supra
DC-XZ6 manufacturer.
