Finally found the time to go though this procedure but to no avail
Mail did rebuild it's database and reimported all the messages but the problem persist. Here it is again:

Anything else I can do ?
Open this path and find a box with .emlx files in it, drag one to Text Edit, does it show up there?
Installed any new Fonts?
If so, try Mail>Preferences>Fonts & Colors & changing the Font(s) used, and restart Mail.
Please understand I'm trying to help you get help faster. Mining up two-year old posts and tagging on doesn't often get you help around here. It is always best in these forums to start your own topic. For your Mail question, find out what Mac OS version you have by doing "About this Mac" and post in the forum for your OS version from this list:
When you post, be sure to post as much info about your Mac as possible, to save helpers having to ask you a question before they can answer yours. Note my equipment line below for an example. Think of it as the same as calling your car dealer's service department when you have a problem. The first thing the mechanic will ask is, "What make? What model?"iMac 27-in; Mid 2010 2.93G i7 Quad, Mac OS X (10.6.8), 12GB RAM; ATI5750 1G VRAM
