 I've been unable to reproduce it from gdb because when I enter the image
digikam hangs and I can't even click the button to rotate the image.

But googling around Ive found this bug (Crash in exiv2 due to assertion when
setting rating on jpg with a Casio makernote):
http://dev.exiv2.org/issues/1106

I'm using Ubuntu Gnome 16.04 with the packages provided by Philip Johnsson, and
I had not installed exiv2. So I tried to install it:

$ sudo apt-get install exiv2
$ exiv2 --version
exiv2 0.25 001900 (64 bit build)

and restarted digikam. Now it's working fine!

This is the log from the console now:

I think the error is in the third line:
***
digikam.metaengine: Exiv2 ( 2 ) :  Directory Casio2 has an unexpected next
pointer; ignored.
***

Maybe updating version of Exiv2::Internal should solve this bug.
