After a migration from Mozilla Mail 1.7.3 to Mozilla Thunderbird 1.0, I've
started noticing corruption in the text body of messages, both from NNTP
newsgroups and in my mail accounts.  

Since I migrated, I've just added a few newsgroups and played with the layout. 
I cannot pinpoint exactly what could have caused this problem.

See the screenshot attachment I'll be adding. The message shown in the
screenshot should appear like this:

Reproducible: Always

Steps to Reproduce:
1. Upgrade from Mozilla Mail 1.7.3 to Thunderbird
2. Read emails and newsgroup posting
3. 

Actual Results:  
Message body display corruption

Expected Results:  
No display corruption

(sorry about that big image BTW, it is the first time I take a screenshot of my
dual display and didn't notice the right part until it was too late).

I just did a test by creating another profile and the messages display ok in
this other profile.

So I went thru both prefs.js and found this difference:

user_pref("font.name.monospace.x-western", "CSD10");

Upon removing this, the message displays correctly!  So I guess it is a
left-over config that shouldn't have been imported to Thunderbird...

I've documented it here:
