   Please see the attached patch that addresses those two issues and
   tries to "skip" those non-existant images when viewing. This
   auto-skipping could be a bit confusing because commands like "seek
   100 images back" don't take these "holes" into account...

   I've also changed one iterator to a constant one. It compiles and
   works fine, so I guess it's a safe change.

It seems to solve the problem.

Note that in any event KPA has to be prepared to deal with nonexistent
images -- an image may be deleted between when KPA scans and when
someone tries to look at it.
