Steps to reproduce:

1. Go to Edit → Preferences → Mail Preferences

2. Under "Message Display", unselect "Use the same fonts as other applications"

3. Choose a Fixed Width Font

4. Restart evolution

5. Open a plain text e-mail


What should happen:

The body of the e-mail should use the font previously set.


What happens:

The font and its size are the default ones. Looking at the source code, I see that Evolution sets -GtkHTML-fixed-font-name. However, looking at source of GtkHTML, I couldn't find such property.

I do not have a deep knowledge of Evolution/GtkHTML, I think that to fix the problem either Evolution should find an another way to set the font (e.g. wrap the text inside a <div style="font: ...">) or GtkHTML should be modified to support the property.
