[Digikam-users] Digikam Crash when changing metadata (rotating, assigning flags or keywords)

[Alan Pater]

There is a bug related to Casio files in the exiv2 library, which is
what digikam uses to read and manipulate image metadata.

http://dev.exiv2.org/issues/1106

It was fixed and will be in the next version of the exiv2.
