Hi,
I noticed this after upgrading to 7.0 (and verified in 7.2):

Certain epubs, while extracting covers by E and book button fail to extract the cover correctly, and even produce rendered red error message (above actual cover image or instead it) in the cover.jpg:

This mentions unknown entity nbsp (the page code contains  , correctly formatted IMO).
I'm not claiming it's a regression in 7.x, but I never saw it before.

My questions:
a) Is this known/expected behaviour of extract cover?
b) Why is code for extracting the cover and actually displaying it different? I mean, sometimes the rendering of the cover is wildly different to the same cover displayed by ebook-viewer. Is it because the extractor and viewer don't share the codebase? Talking only about EPUBs.
