My issue does appear to be related to a know exiv2 bug. However that bug
was supposedly fixed and it appears to me that I have the latest version of
exiv2. Does the info below reveal any packaging issue or anything else I
should alert the Arch ufraw maintainer or packager about? Thanks (and
forgive me if it is not appropriate to continue the conversation here).
