dump_data returns empty stringIO

[koenhandekyn]

on mac os x and ruby 1.9.3 with the current 'latest greatest' branch form active_activepdftk it seams that dump_data returns an empty stringIO

1.9.3-p327-turbo :030 > p.dump_data('~/Desktop/UpNxt.pdf').readlines
=> []

while the following nicely creates the correct data dump in to a file that contains the data.
1.9.3-p327-turbo :031 > p.dump_data('/Desktop/UpNxt.pdf', :output => '/Desktop/UpNxt.txt')
=> "~/Desktop/UpNxt.txt"

for performance and deployments reasons i'd like to avoid (temp) files. is this stringIO behaviour known ? any ideas ?

thanks

patch below. it seems that that the puts command on a StringIO doesn't seem to behave as the author expected (anymore?).

to fix, replace call.rb#196 with

    if @output && !@output.is_a?(String)
      @output.write stdout.read 
      @output.rewind        
    end

Thanks for this patch. I will test this out on multiple ruby versions. I have been testing on 1.8.7 and 1.9.2. It looks like you are using 1.9.3, I will merge and test the patch on all 3 versions, unless you want to.

Did the tests pass for you on this change?
