How do I get DBPedia References to stop crashing immediately after I start it?

I have no idea what the program does, but I'd like to find out.

Welcome to LQ

To know what is DBPedia, see here

What did you install exactly and how? Knowing that we will hopefully be able to understand why it crashes.

Maybe you did install some program not intended for Slackware, like a package for Ubuntu or Ferdora?

I've meant to ask this as well. If you click on the 'DBPedia References' icon seemingly nothing happens.

I dug into the dbpedia_references.desktop file and found "exec=krubyapplication dbpedia_references/dbpedia_references.rb"

From a command line I entered

Code:

krubyapplication dbpedia_references/dbpedia_references.rb

and got

Code:

Is this normal or expected behavior? I'm running 13.37 by keeping 13.1 up with -current, but I've noticed this behavior since 13.0, IIRC, and maybe before.

I did the full installation of Slackware64 13.37 and DBPedia References was one of the programs installed.

I didn't break it. It came like that. lol

I wonder if it is a ruby problem. I've noticed the ruby clock desktop widgets have no hands/numbers. I'm not a programmer though.

Hrm. DBPedia appears to be an environment to set up one or more web pages that allow the user to make queries against wikipedia data. Quite powerful.

I don't think we'll get it to do anything useful for us without web programming skills.
