The line that needs to be changed is line 415 by my count.

I get the same thing once I make the change in line 415 and adjust my test 
code. I'm on Ruby 1.6.7 and Tk8.3.3 (standard Debian 3 .debs).

Interestingly, using a code block still seems to give different results. 
After fixing tktext.rb, I still get decimals instead of strings with:

  text.dump('tag', '1.0', '1.14'){|x| p x}

Putting the code block in an each, however:

  text.dump('tag', '1.0', '1.14').each{|x| p x}

Yields identical return values as your 'p text.dump...' (As expected)

- From my reading, this seems to have something to do with adding the block 
parameter to the call to tk_send (following which lead me on something of 
a goose chase)... which means the problem with the code block may be 
outside of TkText#dump. Perhaps sending the code block outside dump can be 
avoided using a kvis.collect at the end of the method before returning the 
array.
