Code review comment for lp:~and471/inkscape/gallery

Fix for 'directory name = supported file extension' in r10108 confirmed.

Remaining issue - hang with linked SVG image - remains (possibly upstream in gdk-pixbuf (?), though the preview in Inkscape's regular file chooser dialogs works fine), and also occurs if a filter uses 'feImage' and links to an SVG file (via filter editor):

    <filter
       id="filter11"
       inkscape:label="filter1"
       x="0"
       y="0"
       width="1"
       height="1">
      <feImage
         id="feImage13"
         xlink:href="/Users/suv/tmp/stars-3.svg" />
    </filter>
