Add to Any plug-in problem

Just to add a bit more info. The problem only occurs on pages using excerpts (e.g. archives), and (with default settings) only on posts where there are fewer than 55 words text. Since this is a photography website there are frequently posts with very little text.

I’m using a custom ‘excerpt_length’ function to limit excerpts from 55 to 20 words, but on any posts with fewer words than that the problem remains.

It can be partially resolved by deselecting the “Display Share/Save button at the bottom of posts on the front page”, but that’s not an ideal solution as I’d rather have that option for the blog front page.
