Blog is broken!

Oh dear.....

Something that blogger.com have done has broken the layout of my blog..... not good.

As far as I can tell the following tags have been added :

< div style="clear: both;" >< /div >
AND
< div style="clear: both; padding-bottom: 0.25em;" >< /div >


and they are enough to wreck the layout of my blog in Firefox. I have sent a message to blogger.com but am not expecting a speedy reply....
