"File conflict" string and Header Capitalization
IMHO "File conflict" string, according to GNOME HIG, it should use Header Capitalization.
Header capitalization should be used for any headings, including headings in header bars, tab titles, and view titles. It should also be used for short control labels that do not normally form proper sentences, such as button labels, switch labels and menu items.
