no implicit conversion from nil to integer (TypeError)

I'm on RHEL6, and trying to run jasmine-headless-webkit so I can get my jasmine tests into a Jenkins CI installation.

I see this error and I have no idea where to go next.

In general, what does
[jasmine-headless-webkit] no implicit conversion from nil to integer (TypeError)
...imply is happening?

Am I missing a package or gem?
I've included a list of my Qt and Xvfb packages below.

Note that I did have to link "qmake" to the qmake installed:

ln -s /usr/bin/qmake-qt4 /usr/bin/qmake

Here's what my command looks like:
$ xvfb-run jasmine-headless-webkit -c -j test/jasmine.yml

I've altered jasmine-headless-webkit-0.8.4/lib/jasmine/headless/command_line.rb -

          if options[:do_list]
            FilesList.reset!

            files_list = FilesList.new(:config => runner.jasmine_config)
            files_list.files.each { |file| puts file }
          else
            $stderr.puts "BLAH!!"
            if runner && runner.run
              exit runner.run
            elsif runner
              $stderr.puts "runner but no runner.run"
            else
              $stderr.puts "runner failed!"
            end
          end

now the error is:

$ DISPLAY=:0 jasmine-headless-webkit --runner-out jhw-out.html
BLAH!!

UPDATE: I've pulled out the command run in the "system" call in runner.rb .
Looks like /jasmine-webkit-specrunner is failing:

It would be swell if there was something detecting this kind of Qt or driver problem in jasmine-headless-webkit , or -specrunner .

[arapehl]

Has this been solve? I just installed jasmine-headless-webkit on Mountain Lion and the latest qt (4.8.3) with homebrew and I'm getting the same error.

[timdiggins]

For future reference think that @arapehl's problem with Mountain Lion is actually qt compatibility - you need to install qt 4.7 see #101
