Description Miklos Vajna 2014-05-01 13:16:12 UTC
Steps to reproduce:

1) Open the attached document

2) Make sure the Writer window has a low enough width: reduce it until the horizontal scroll-bar appears.

3) Scroll down to the first empty line, and click on it, so the cursor gets moved there (it's between A41 and A43).

4) Hit backspace to delete the line.

5) Hit page down a few times -> crash.
