Comment 2 for bug 1037669

I looked quickly and couldn't figure out a way to fix this decently; looks to me like the actual parsing in webkit is happening in a very different part of the code than the bits that handle whether to show as plain text or not, so fixing this (keeping in mind that plain-text stuff is a module), appears non-trivial.

I opened a bug upstream since we'll need help from the Evolution developers for this one; see https://bugzilla.gnome.org/show_bug.cgi?id=684245
