Comment # 7 on bug 1204409 from Geoff Kuenning

I don't think the fix is correct; in some cases jhead appears to invoke helper
programs incorrectly.  Consider:

[take a photo in portrait mode and download it]
bow:2:636> jhead -autorot IMG_2132.JPG 

Nonfatal Error : 'IMG_2132.JPG' Command has invalid characters.

That message does not come from jhead, nor from jpegtran (which it invokes). 
I'm guessing the shell but I didn't have time to debug it further.

This behavior is new in Leap 15.4.
