Apologies if this shows up twice - tried entering it before logging in and don't think it worked.

There is another workaround to this problem if you're not ready to upgrade MW 1.15, described in this post on mozillazine.org.

Remove or rename the KTHMLFixes.css file in the skins/SKINNAME directory.

I am running MW 1.15 and wasn't ready to upgrade yet, so this was helpful. Monobook is the default skin I use. I noticed that the problem went away with a different skin (Modern), and confirmed that there is no KHTMLFixes.css in the skins/modern directory.
