Bug Description

My epub contains "font: normal 0.6em/135% arial,helvetica,verdana,sans-serif"

The font-size information 0.6em/135% does not make it into the final epub, the resulting font is a lot bigger than in the original.

And note that fonts are resized by the conversion. You
can turn it off via the look & feel section of the conversion dialog.

It is copyrighted, but an issue available for testing purposes, I'm not sure I can attach it without making the bug private. I will do so if you think it neccessary.

Search for "taz E-Book Generator Version 4.00" and compare the relative font-size with the original.

I tried ebook-convert --disable-font-rescaling, but no avail.

I think the problem is in oeb/normalize_css.py

line 128: vals = [x.cssText for x in cssvalue]

breaks it down to:

[u'normal', u'0.6111em', u'135%', u'arial', u'helvetica', u'verdana', u'sans-serif']

And the following loop breaks after recognizing 135% as font-size.

Fixed in branch master. The fix will be in the next release. calibre is usually released every Friday.
