[gedit] Avoid crash when removing the highlighted text.

commit 65f38face0b393c227b0077c03bd173dba4f4aed

    Avoid crash when removing the highlighted text.
    
    We must block the changed signal when setting "" in the entry
    to avoid an useless search and a crash as the text mark for the
    start of the text is deleted when the popup is hidden.
