[Pkg-shotwell-maint] Bug#763549: libgexiv2-1: Python 3 and GExiv2 ImportError

[Luis Felipe López Acevedo]

Package: libgexiv2-1
Version: 0.4.1-3
Severity: normal

Dear Maintainer,

I am trying to use Python 3 and GExiv2 in Debian 7, but I get an import error.
I don't know what am I doing wrong or if there is a bug in Exiv2 or GExiv2
installation.


## Steps to Reproduce

1. Copy the code example in GExiv2 Python Support page. [1]
2. Save the code in a file called ``gexivwrite.py``.
3. Run the code with Python3:

   $ python3 gexivwrite.py


## Expected Behavior

The code should run without error and the metadata should be applied to the
image.


## Unexpected Behavior

An ImportError occurs:

    $ python3 gexivwrite.py
    ERROR:root:Could not find any typelib for GExiv2
    Traceback (most recent call last):
      File "exiv2meta.py", line 3, in <module>
        from gi.repository import GExiv2
    ImportError: cannot import name GExiv2

## Aditional Information

(G)Exiv2 is not referenced in gobject-introspection:
