Link to old thread:
http://thread.gmane.org/gmane.comp.freedesktop.poppler/8683

I've investigated this briefly. An observation:

http://cgit.freedesktop.org/poppler/poppler/tree/glib/poppler-page.cc?id=poppler-0.33.0#n825

The sel_text->getLength() is 1283 (which doesn't match with the 1261 from
poppler_page_get_layout).

If I change this to use a g_strndup() with the correct length:

result = g_strndup (sel_text->getCString (), sel_text->getLength());

And then look at result[696:], then I find that the rest of the string is
filled with 0 bytes.

I'm extremely keen to get this fixed, so any pointers would be appreciated.
The rate of encountering this bug is increasing all the time!

Thanks,

- Peter
