title: ImageButton does not display a particular drawable
body: <p>This is rather a funny problem I have ever come across,</p>
  
  <p>I have a table layout with 9 image buttons, 3 per row. Every ImageButton has a different image associated with it. I have set the background of the image button to transparent (#00000000). Now here is where the funny stuff happens, One of the images doesn't show up on the emulator (Gingerbread) as well as a device running Froyo. The layout editor shows all the images in place.</p>
  
  <p>Here are some more stuff:</p>
  
  <ol>
  <li>I used a <code>RelativeLayout</code> instead of a <code>TableLayout</code>, the same issue persists.</li>
  <li>I changed the position of the image (used it on different buttons) and still it doesn't show up.</li>
  <li>When I use a different image they show up, but when I use this particular image it won't.</li>
  <li>All images have the same resolution (90x72) and density (72ppi)</li>
  <li>All the images are in the the <code>drawable-mdpi</code> folder.</li>
  </ol>
  
  <p>Any pointers?</p>
