 As written in the summary: get_image_send_to_editor() uses (as many other
 functions) the function esc_url() to escape (at least that is what the
 name suggests) and URI. But the function name is misleading. Because of
 the (no-) implementation of any kind of escaping in esc_url() but using
 clean_url() instead which filters out various characters by undocumented
 principles this deletes complete valid URIs instead of encoding them.

 Example URL: {{{http://192.168.2.106/wordpress-trunk/wp-
 content/uploads/2009/09/Auto-na-dálkové-ovládání.jpg}}} is "escaped" into
 an empty string {{{string '' (length=0)}}} when used in esc_url().

 This is a Blog with an output encoding set to UTF-8.
