1. I could not find the "FictionBook Backend" in the menu. So I am writing to "general".
2. My Synaptic does not show any update for my "Version 0.19.3; Using KDE Development Platform 4.13.3" nor "Fiction Book Backend Version 0.1.5"; these version too are not available in the bugtracker menu.

3. THE PROBLEM. When presenting a Fictionbook file Okular does not collapse extra spaces between <p> and </p>; it does not treat line breaks in the source text as a space. As a result a structured source text is rendered with unwanted spaces and newlines. This is a deviation from XML Spec (Section 2.10: White Space).

4. Another problem is that the <text-author> element is silently ignored.

Reproducible: Always

Steps to Reproduce:
1. Please download a test book (1.2k):   http://pok.heliohost.org/unix/t.fb2
2. Open t.fb2 in Okular.



Actual Results:  
What I see with Okular is   http://pok.heliohost.org/unix/okular.png
Please note unwanted line break after "One"; unwanted spaces before "two" and "six".
Please note the missing attribution of the quotation.

Expected Results:

Basically, something like this:

| One two three.
| Four five six.
| Nine.
