Isn't this the following known issue from PROBLEMS?

  ** Certain keys such as 'C-S-u' are not reported correctly.

  Some keys with modifiers such as Shift and Control might not be
  reported correctly due to incorrectly written GTK input method
  modules.  This is known to happen to 'C-S-u' and 'C->', which are
  misreported as 'C-u' and '>'.

  To disable the use of GTK input methods, evaluate:

    (pgtk-use-im-context nil)

  This will also cause system input methods and features such as the
  Compose key to stop working.

  On X Windows, users should not use Emacs configured with PGTK, since
  this and many other problems do not exist on the regular X builds.
