Thanks for your bug report. Sorry about the delayed reply but I recently returned from being overseas for a couple of months. When I go to this page the NRW format is not listed: http://dev.exiv2.org/wiki/exiv2/Supported_image_formats
However I have tested a sample file, and based on my tentative testing exiv2 on Ubuntu 12.04 seems to read the metadata ok. So I will add it to the list of supported formats. If users reports bugs and/or crashes with that format further action will be required. In the past older versions of exiv2 have crashed when reading certain formats.
