[BUG] Latest CVS (r2701) has a editor bug in firefox!

[xeditor]

Hi there.
Don't know if this is the place to post this but please move me to the right place.
I just started to use the r2701.
It works well except for one error I found.
If i use Firefox 3 and change the font and size of the text I get a the following error when I reciev the mail.

Just for your info.
