I have post indexer v3.0.4 on wpms 3.5.1. My error log

Hi, I have post indexer v3.0.4 on wpms 3.5.1.

My error log is getting full from errors like the following, due to high traffic site.

Duplicate entry '%ce%b4-%cf%84%ce%ac%ce%be%ce%b7' for key 'slug' xcexb2xcexacxcfx83xcexb7xcfx82 xcexb4xcexb5xcexb4xcexbfxcexbcxcexadxcexbdxcfx89xcexbd WordPress xcexb3xcexb9xcexb1 xcexb1xcexafxcfx84xcexb7xcfx83xcexb7 INSERT INTOwp_network_terms(name,slug,term_group) VALUES ('xcex94\' xcfx84xcexacxcexbexcexb7','%ce%b4-%cf%84%ce%ac%ce%be%ce%b7',0) xcexb1xcfx80xcfx8c post_preview, wp_create_post_autosave, wp_update_post, wp_insert_post, do_action('save_post'), call_user_func_array, postindexeradmin->index_post, postindexermodel->index_tax, postindexermodel->insert_or_get_term, m_wpdb->query, referer: http://blogs.sch.gr/myblog/wp-admin/post.php?post=236&action=edit

I guess its a bug of post indexer, but can’t locate it in order to fix it.

Can you please “ping” the developer about it?

Thanks in advance.
