[orca-list] orca skips text while reading a large file using libre office

[sathyan <sath linux gmail com>]

Dear list,
I was reading a text file of more than ten thousand lines length. After 
reading 300 or so lines then it reads the last chapter. I checked the 
accessibility in tools menu. I use libre office 4.2.8.2 and orca from 
latest master.
What to do. any suggestion.
I tried with open office and it shows same problem.
