   Do you have a tool for inspecting the clipboard contents? In   
   particular, listing the different formats in which the clipboard   
   contents are being offered? That might shed more light on what exactly   
   is going on.   
      
   Here are some examples from my Linux system.   
      
   * Copying some text from Emacs:   
      
       ldo@theon:~> wl-paste -l   
       GTK_TEXT_BUFFER_CONTENTS   
       application/x-gtk-text-buffer-rich-text   
       text/plain;charset=utf-8   
       UTF8_STRING   
       COMPOUND_TEXT   
       TEXT   
       text/plain   
       STRING   
       text/plain;charset=utf-8   
       text/plain   
       SAVE_TARGETS   
      
   * Copying some text from a web page in Firefox:   
      
       ldo@theon:~> wl-paste -l   
       text/html   
       text/_moz_htmlcontext   
       text/_moz_htmlinfo   
       text/plain;charset=utf-8   
       UTF8_STRING   
       COMPOUND_TEXT   
       TEXT   
       text/plain   
       STRING   
       text/plain;charset=utf-8   
       text/plain   
       text/x-moz-url-priv   
       SAVE_TARGETS   
      
   * Copying the same text from the same web page in Chromium:   
      
       ldo@theon:~> wl-paste -l   
       chromium/x-source-url   
       text/html   
       STRING   
       TEXT   
       UTF8_STRING   
       text/plain   
       text/plain;charset=utf-8   
       chromium/x-internal-source-rfh-token   
       text/plain;charset=utf-8   
      
   * Copying the above text from KDE Konsole:   
      
       ldo@theon:~> wl-paste -l   
       text/plain   
       text/html   
       text/plain;charset=utf-8
