File is not readable or doesn't exist

Running digikam-select on openSUSE 42.2 results in the following error:

ruby digikam-select.rb -i /home/dmpop/Pictures/digikam4.db -o /home/dmpop/Pictures/export/ -r5
{:albums=>true,
 :mode=>"copy",
 :inputdb=>"/home/dmpop/Pictures/digikam4.db",
 :output=>"/home/dmpop/Pictures/export",
 :minrating=>"5"}
ERROR: File /dmpop/Pictures/20150531-161618.jpeg is not readable or doesn't exist
ERROR: File /dmpop/Pictures/20170128-133219.jpeg is not readable or doesn't exist

Both files exist in the specified directory.

That's strange. This error will only appear if the source file fails both File.exist?(f) and File.readable?(f) in Ruby. Do the access modes (post output of ls -la) really match?
What does ruby -e 'puts File.readable?("/dmpop/Pictures/20150531-161618.jpeg")' return?

ruby -e 'puts File.readable?("/dmpop/Pictures/20150531-161618.jpeg")' returns false, but ruby -e 'puts File.readable?("/home/dmpop/Pictures/20150531-161618.jpeg")' returns true. This leads me to believe that the missing /home is the culprit.

Probably. Can you rerun with -v? (empty destination dir beforehand)
Also activate (uncomment) line 196 in the script (debug 2, file.inspect, ...) before hand. Thanks!

Enabled debugging, then ran ruby digikam-select.rb -i ~/Pictures/digikam4.db -v Here is the output:
