This problem did not happen before Version 5.1.0b (Build 4905)

I told campaigns to send this email:

It ended up sending this email, adding a =3D style tag to every styled element and destroying my inline css file by haphazardly adding urls after every letter.

I removed the FCK editor and replaced it with tinymce. I have been doing this with every build of SugarCRM since 4.5 without any problems. I do not believe the two are involved as after I save the page it displays fine in the campaign preview. Only after I send the email is when the problems start.

Could someone suggest what the problem might be? I might have to go with mail chimp on this one.
