Please enable all debugging for digikam in kdedebugdialog, run digikam in the
console, try to load such an image and paste the console output here.

By uploading that sample file here I just realized that it is indeed a png
wrongly named .jpg - renaming it to .png solves the issue. Maybe you could look
into loading such files anyway or even offering to rename them? Otherwise
consider this solved.

Same problem here with Digikam 2.7 under OpenSuse 12.1 but only with TIFF files
without a single exception (+8000 images).

Created attachment 97166
  --> https://bugs.kde.org/attachment.cgi?id=97166&action=edit
imageLoader.patch

When image loading fails with a default loader and the query was not been
canceled, we use the QImage loader. The QImage loader now uses only the file
content for the format detection.
