I keep getting this error on the example.rb

gphototest.rb:30:in `save': LibGPhoto2 function returned: Unspecified error (GPhoto2::Exception)

Here's the full output. I've tried with both ruby 1.9.3 and 2.2.0.

After commenting out the preview capture in the example.rb everything is working great.

cams.first.capture.save :type => :preview, :new_name => "PREVIEW.JPG"
