Description Bengt Thuree 2006-09-16 13:15:20 UTC 
After importing a photo with existing tags I get the following in the UserComment field.

    <rdf:Description>
      <ns2:UserComment>
        <rdf:Alt>
          <rdf:li xml:lang="x-default">&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;&#x0;</rdf:li>

hmmm I need to look into this deeper.
Comment 3 Maxxer 2007-12-02 09:22:24 UTC 
I get those descriptions even when importing directly from camera.
Comment 4 Maxxer 2007-12-02 10:37:05 UTC 
If it can be useful, this is what exiv2 -v -p h says about UserComment of an imported image:

0x9286 Photo        UserComment                 Undefined 263 263
(Binary value suppressed)

\0 values are the "unused" part of the comment. Shouldn't we strip those values off of the result string, in src/Imaging/Tiff.cs:441?

strip-zeros-from-comment-field.patch

this patch simply adds a .Trim('\0') to the return value.
