PDF test case
Originally reported in <a href="https://bugzilla.gnome.org/show_bug.cgi?id=659730">https://bugzilla.gnome.org/show_bug.cgi?id=659730</a>
"[...] there are some documents, which after a text is selected in
evince make it freeze. The same documents can be opened and scrolled as long as
a text selecting tool is not used.
How to reproduce the bug:
- Open one of the above pdf documents and try to select text
Note: If the selected text is a word or a line , the application freezes for a
while and then continues to work. If a paragraph or more is selected it totaly
freezes and even slows down the whole machine."

However, I have not been able to get Evince or poppler-glib-demo frozen.
However, the selection is slow and it seems to select some blocks (squares)
that involves 2 or 3 lines.</pre>
