I moved to okular for my epub readinng so the issue is of lesser importance for me. A couple of other issues I noticed while using fbreader:
1. Fbreader kept centering the text in all lines on all pages, that was really annoying. Not sure why fbreader does that, I edited the CSS that came with the book and changed all "center" tags to "left" and changed internal fbreader settings for paragraph and headers to use "left" alignment yet fbreader still continued to center the text. When opening epub's html pages with browser they show up properly left aligned. 2. Fbreader is missing shortcuts that a GNU/Linux app is expected to have, for example, Ctrl+Q to quit the app. 3. Add spacebar to be the same as PgDown.
