_icl_content_fix_image_paths_in_body is breaking image urls

In my nodes, I have some PHP-filter code similar to:

print base_path() . path_to_theme() /images/myimage.jpg" />

When I save the node, icl_content modifies this by putting a forward slash right at the beginning of the src:

print base_path() . path_to_theme() /images/myimage.jpg" />

This is causing double forward slashes in the image src and breaking in some browsers.
